Question about Maytag Dishwashers

Open Question

I have a maytag mdb7100aww. The dw fills with water and starts the prewash cycle. After the dw empties for the first time it will not refill with water again. The dw then continues as though there is water in it. The point being is that there isn't any water in the dw and I have to refill it manually. ARRG!!!!!!!!!! If I do this then the dishes come out perfectly clean. I have taken the spinning arms that distribute the water out and cleaned them of small bits of plastic. I have also taken the dw apart all the way down to the bottom filter (used a nut driver to remove the 1 1/2" bolts). I can only think that it is the float switch. How do I remove it without breaking it?

SOURCE: Maytag MBDF550Aww upper spray arm doesn't spin.

Cleaning the filter was the right thing to try.
Since you don't see cracks/breaks on the spray arm and it appears that it is spinning freely, I doubt that replacing the spray arm will fix your problem.
If your dishwasher is several years old, your problem is likely a failing pump motor, but before you swap that out, check that the impeller is not damaged. Good Luck!

Hello there:
I will post this in 2 seperate post's due to the length of this answer and possiable solutions ok?
If your dishwasher is cleaning poorly, check these: 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

Multi-Screwdriver

Pliers

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.

Maytag dishwasher model mdb7100aww, no water input,all else appears ok


Check that your supply faucet is open, Check if there is a screen in the supply line, these can become blocked due to scale deposits from the mains. If there is no screen check that the inlet solenoid valve has not got blocked. If none of the above help, check that there is power getting to the solenoid valve when the machine is supposed to be on the fill cycle. If no power is getting to the valve, the timer might be faulty. (You can try hand filling the machine and see if it goes through a cycle, at least up to the rinse stage, this will tell you if the timer control is working). Please rate this solution.

Dishwasher soap still in door after wash cycle, so dishes are not very clean. Soap dispenser cover is sprung open but soap (on both sides, wash and prewash) is still mostly where it was poured, only now...


Check for the right amount of water in tub. In this unit close to the lip of the tub after fill. If water fill is correct check movement of lower spray arm. Other possibilities delayed action of dispenser from defective wax motor. Most probable is wash motor. Start unit after fill and when was starts, open door and see if water is being pushed to the top rack and dripping from the top of tub. Motor is easy to install.

Kenmore dishwasher will not fill with water model no 630.1609406. It will run a full cycle but not fill. Water was temp shut off to replace kitchen sink and now dishwasher won't fill with water. No fill...


First, are you sure that the machine is not filling?
I go on calls all the time for this problem and it turns out than the machine fills but the wash motor does not run.This leaves soap in the bottom of the DW so it looks like it did not fill with water. This is a common problem in dishwashers that have not been run for a few months, and is quite common after a remodel. If it IS getting water, the motor is probably stuck. If it is Not getting water the first step is to locate the "over fill" float inside the dishwasher. This will be a round sort of mushroom looking thing on the floor of the machine near the door on the right or left. Make sure it moves freely up and down. It will only move about 1/4 inch but If it is stuck up, the machine will not fill. If float is O.K. then check the water source. Turn of water to DW. Remove the kickplate under DW door and disconnect the waterline from fill valve (should be on front left side of unit). Run waterline into bucket then turn on the water. If you don't get water call your plumber. If you get water then you need to check the fill valve. Connect a volt meter to the 2 wires on the fill valve. Start DW. First the diswasher should start draining, then it will start filling. At this point (a few minutes into the cycle) you should see 120v AC at the fill valve. If you do see 120v Ac, replace the valve. If you don't , then turn off the machine and check the float switch. This is located under the DW right under the mushroom thingy. The switch should have continuity when the DW is empty. If there is no continuity then replace the switch.

The first cycle water is not hot - all other cycles are hot - the water in the sink next to the dishwasher is not???


Where does the dishwasher connect to hot water? If it is connected to cold it must be changed. From your description, the water is coming from a long way off and has to warm the pipes as it travels to the dw. The dw should have a heater to bring the water up to temp after filling before it runs, if this heater is not working, the first run will be cold and the next hot because you have drawn enough water through the pipes to bring hot water to the dw.
1. Change where the dw gets hw.
2. Run hw in the sink before allowing the dw to start (if connected to same line).
3. Fix the dw's water heater.

Three possible fixes. Good luck.

DW fills and empties, but, in between the sprayer never comes on. There is absolutely no sound as the timer goes through the spray/wash cycle.


start the unit and open the door after abt 3 mins and look for water inside.if water is there and u dont hear water spray sound when running but only a low humming sound the motor is bad.if there is no water then chk for anything stuck under the water float.if that is ok then there is problem with fill valve.

Dirty racks


What is the manufacturer and model number of the dishwasher?
Here is the process I would follow to remove the gunk.
Start a short cycle in the dishwasher, without adding detergent powder and after the (hot) water has filled the DW and the wash cycle has begun, open the DW door and add 1/4 cup of household bleach. When the water drains and begins to refill for the 2nd wash cycle, check the dishwasher to see if anything has gotten better and if not, add another 1/4 cup of bleach as soon as the hot water has refilled. Allow the DW to finish the full cycle.
Begin another short wash and as soon as the initial hot water fills and the wash cycle begins, open and add 2 cups (approximatly) of white vinegar. Allow the whole set of cycles to finish and check the insides.
If grease remains, I would use a de-greasing spray (avilable at all hardware stores and most food stores.) Spray on and use paper towels on all surfaces.
Because I do not know the make and model # for your dishwasher, I can not give you a part number for replacement racks.
Good Luck!

Water leaking onto the floor


1. If the water is going onto the floor during the drain cycle there is either a hole in the hose or it is completely loose from the DW or a hole in the drain assembly under the sink but if that were the case you would have water under the sink also.
2. If it during the wash or rinse cycle then the seals are not sealing (door is not closed all the way or seals are bad) or the float at the right front of the DW is stuck allowing the DW to overfill with water.(you need to open the door and pull the float up and out as you do so push it up and down and listen for a clicking sound.(which indicates it is making contact with the fill solenoid)..if you here the clicking and the float is full of gunk (old soap and such) clean it out and replace it and run it through a cycle and monitor the DW to see if the fill cycle shuts off before the water reaches the overflow point.
3. the only other option is a possible rust through on the DW and or the drain and motor mount in the center of the DW where the food particles and water are drained...is loose and leaking or rusted through...(how old is the DW).
4. Also check to see there are no large particles around the door seal to prevent complete closure and sealing of the door seal. As well as the door latching properly (when closed can the door be moved or pulled open)?

I hope this helps and let me know if not Please relay model number, age and other specifics you feel are pertinent...thank you and please rate me if this helped...thanks again ...the Fang
