Not enough water

I've changed the water lines, cleaned the fill valve and find nothing. I replaced the timer, and still very little water in tub! Checked the float, looks good. This model seems to fill by timer not float. It works great when I manually add water. Any ideas?

Re: Not enough water

It is the pressure switch that controls the water level, it is also a switch connected to the motor,once the contact triggers so prematurely, your water level will not reach its designed level, or check the pressure.

Re: Not enough water

Shut off the water valve to the dishwasher. Disconnect the water line at the dishwasher, place it into a bucket, and open the valve to check the water flow.

Re: Not enough water

Be aware that you should remove dishwasher's power cable before touching wires or making resistance measuring !!! Check that the inlet valve get power. In case it does and no water entering the tub, check with multi-meter for solenoid's resistance (disconnect first the wires to it),if no measurement result, you should replace the valve. In case you have a measurement result, remove the solenoid from the valve and check that it's clean from any dirt. In case there is no power to the inlet valve - check that the float switch works. This is usually a small switch attached to a float. The float (usually a cylindrical) located inside the dishwasher at the bottom. As the water level rises, the float rises too. When it reaches the certain height, the float activates its switch, which cuts the electricity to the water inlet valve. If the switch is defective (stuck in the disconnected position)it will prevent power from the inlet valve. The switch is an On/Off switch and you can check it easily by a multi-metr. Good luck !!

SOURCE: dishwasher filling correctly?

john, the dishwasher has a timed fill, make sure you are using 3/8 inch line. If you are using 1/4 inch, that would be your problem. The fill should be just below the heating element. If you are using the 3/8 inch line, the next suspect would be the fill valve itself. Make sure nothing is kinked, Catriver.

SOURCE: Water Pressure Too Low in Washer -- Pump going bad?

Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.

Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

Tools required:

Adjustable wrench



Step 1. Disconnect the dishwasher from its power source.

Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.

CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.

Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here.

Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home.

Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s).

The inlet valve is usually near the front of the dishwasher. Attached to the valve you’ll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher.

Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel.

CAUTION: Water supply line may be hot.

Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.

Step 6. Remove the screws holding the valve to the dishwasher frame.

Step 7. Label the wires to the valve so you’ll be sure to reattach them correctly.

Step 8. Remove the wires from the valve.

Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve.

Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly.

Step 11. Install the new valve in the reverse order of the removal instructions.

Note: The water supply line is under high pressure. Be sure to tighten the fittings properly.

Step 12. Turn on the water to the machine, and check for and correct any leaks.

Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test.

Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle.

Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

  • Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.

  • Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.

If your filter is clogged, it may be causing the cleaning problem.

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

If the detergent cup isn't opening, see the "The detergent cup doesn't open" section, below.

Dishwasher slowly fills after cycle

If water slowly fills in the tub when not in use.

a) Most likely your machine inlet water valve not seating properly and closing. Change the machine water valve.

b) May be sink drain water back flowing to the tub. But you have checked that.

So it has to be the machine inlet water valve.

Maytag performa dishwasher, model # PDBL390AWB.

Sounds like to me you have a water restriction somewhere. Double check and make sure that the main water valve coming into your home is fully open. Make sure the water shut off valve(s) going to the dishwasher both have adequate water flow and that means testing them before being connected to dish washer. If that checks out okay, possibly the plunger that opens and closes in the electric water solenoid is sticking and not opening up al the way since the unit has been in storage for all that time. Sometimes tapping on it when it is in operation can free up that sticking plunger and you may get full water flow restored again. If not, solenoid may have to be replaced. Hope this helps out.

The first cycle does not have hot water - the sink right next to it has hot water - the other cycles have hot water???

Most washing machine timers are digital or mechanical. The timer controls most of the operations of the washer: water level, tub filling and emptying, length of cycles, and cycle setting sequences. For this reason, any repairs to the timer should be made by a professional service person. However, there are a couple of checks you can make when you suspect the timer is faulty -- you may be able to install a new timer yourself.

Step 1: Unplug the washer. To access the timer, remove the control knobs and the panel that covers the controls. This may be a front panel, or access may be through a panel at the back of the unit. Carefully examine the wires that connect the timer to the other parts of the washer. If the wires are loose or disconnected, try pushing them into position; they usually fit into their terminals like plugs. Use long-nosed pliers to avoid breaking the wire connections -- never pull a wire by hand.

Step 2: To test the timer, use a VOM set to the RX1 scale. Disconnect the power leads to the timer and clip one probe of the VOM to each lead. The VOM should read zero if the timer is working. Since the timer is a multiple switch, turn it through its cycle and test each pair of terminals in turn. The meter should read zero at all of these points. If one or more readings are above zero, the timer is faulty and should be replaced.
Step 3: To replace the timer, unscrew and disconnect the old one. Install a new timer made specifically for the washing machine. If there are many wires on the timer, have a helper hold the new timer next to the old one as you work. Disconnect the old wires one at a time, connecting each corresponding new wire as you work, to make sure the connections are properly made. Or, draw a diagram showing the connections before removing the old timer. After all the wires are connected, check the connections again for correctness and screw the timer assembly into place.
In the next section, we will examine two of the most crucial elements of a washing machine -- the water inlet valves and the agitator.
Servicing Water Inlet Valves
If the washer won't fill or fills very slowly, if it overfills, or if the water is the wrong temperature, the water inlet valves could be faulty. These components are easy to locate and very easy to replace, at little cost. When you suspect an inlet valve is faulty, first check to make sure the water faucets are fully turned on and properly connected to the hot and cold inlets of the valves. Then check the screens in the valves; if they're clogged, clean or replace them. If water doesn't enter the tub, set the temperature control to the HOT setting. If there is no water, set the control to the WARM setting. If all that comes out is cold water, the hot-water inlet valve is faulty. Reverse the procedure to test the cold-water valve, setting the control first on COLD and then on WARM. If the tub overfills, unplug the washer. If water still flows into the tub, the valve is stuck open. In any of these cases, the valves should probably be replaced. To check the valve assembly:

©2006 Publications International, Ltd.
If an inlet valve is faulty, check the water connection and the
valve screens. Try gently tapping the solenoids;
if this doesn't work, replace the inlet valve assembly.

Step 1: Remove the back service panel and disconnect the hot-water and cold-water hoses to the valves.

Step 2: Remove the hoses connected to the valves inside the cabinet. Also disconnect the wires from the terminals. Back out the screws holding the valves to the machine. The inlet valves have solenoids (a coil of wire that carries a current) inside the housing. These can be tested, but chances are the valves are simply worn out.

Step 3: Tap the solenoids with a screwdriver handle. If this doesn't work, replace the entire inlet valve assembly. Repairs usually cost more than a new part. Make sure the replacement valve assembly is exactly the same type as the old one. Install it in reverse order of the way you disconnected the old one.

My dishwasher seems to start ok then the first light starts flashing and it do'es nothing just stays there any ideads what my problem is

Can you tell if it's filling with water. The first thing it does is fill with water (usually on a timed cycle) before the pump starts. If there's no water in the tub, it obviously won't wash dishes, since a dishwasher is nothing more than an enclosed pressure washer. If it does not fill with water, you may have a bad fill valve or the timer that turns the fill valve on may be defective. You DO have the water turned on, RIGHT?

Insufficient water in the dishwasher for spinner arms to operate

If the machine functions properly when you add water, then it is likely there is a problem with the water supply. Start at the valve under the kitchen sink.
First I would turn that valve off and remove the water line. Then turn the valve on slowly. Use a small bucket or a large cup to catch the water. You should also have a lot of towels on hand.
If you are not getting much water through it, you may need to change that valve. If you are getting a good flow of water through it, inspect the water line checking for crimped or crushed parts. (is the line copper? braided steel?)
Reconnect the water line to the valve and disconnect it at the dishwasher. Now flush water through the line. how is the flow?
Lastly inspect the water inlet valve on the machine. I found a walkthrough for that at
Actually, you might want to check that first. It may be as easy as cleaning a screen. I'm a plumber, not an appliance tech, so I tend to take a global approach to water supply.
Best of luck

Dishwasher won't fill

The only three things left are:
Is the flow to the fill valve adequate...kinked line...for instance.  Drain valve is partly jammed...letting water out early or timer is bad..I'd go with the valve.  You may be able to clean it out.

Water problem

Many dishwashers will drain at the beginning of any cycle.
If the water does not fill after the pump-out cycle, then the problem is either the fill valve or the float switch. You should be able to hear the float switch click as you raise or lower it. The fill valve usually hums whenever it has power.
If the fill valve has power but doesn't open, (use a voltmeter) replace the fill valve. If there is no power at the float switch, nor at the fill valve after pumping out, then the clock / timer is at fault.

Not enough water in tub

Mderford, on a normal fill, the water should be just above the filter screen. 1.8 gallons first fill, 1.7 on all other fills. Don't think it would be a siphoning problem as you are not having this on the pots/pans. Check the float, make sure it is not sticking. You can check the inlet valve filter screen to see if it is not plugged. Run it through the diagnostics cycle by pushing high temp-air dry-high temp-air dry. Some models it's heated dry-normal-heated dry-normal. It will run through a self test for about 20 minutes. See if any error codes come up. Fill time should be approx. 1:30 to 1:40 seconds. If any of the aformentioned doesn't turn up any results, then it's possibly a faulty fill valve drive circuit on the control back.
