This is either the inlet valve (solenoid valve) or the timer. Water is not pumped in, it flows in under it's own pressure when this valve opens.

On the solenoid valve there are two electrical connections, you could remove these (often spade connections) and connect a mains supply - if it opens then the valve is fine so it is the timer.

A solenoid valve is a cheap and easy to swap component and any DIY'er can do it. It is located right by the inlet pipe (it is part of the inlet pipe assembly) the screw part which the cold water pipe is attached to is the solenoid inlet valve.

Bosch dishwasher cycle running too long?


Please supply model number and define what is "too long". Long cycle times are usually caused by a water heating issue. Some (heavy wash w/high temp heating) cycles may take 90+ minutes for a complete cycle, this is normal. Does the unit circulate (pump) water or is just the drain pump running?

Hi I have an Bosch SGs43c02gb/35 and it does not drain all of the water out when it has finished the cycle, I have cleaned the filters out which were relatively clean and run it with a dish washer cleaner...


Hello

It is quite common for a dishwasher to not drain because either the drain hose or the air gap (if the unit has one) is clogged up. Drain hose clogs commonly occur where the hose is attached to the main household drain line, or where the hose connects with the garbage disposer. Try removing the drain hose to unclog any debris. Don't forget to reattach the hose before you start your dishwasher again.

The pump assembly is comprised of a pump, wash impeller, and drain impeller. The pump ejects the water from the unit, the wash impeller pushes water through the spray arm, and the drain impeller directs the water towards the drain port. Examine your dishwasher's pump assembly. Clean out any debris that may be blocking it. Replace the pump assembly if any of its parts appear to be worn or defective.

It isn't very common, but sometimes a dishwasher's pump assembly is driven by a belt. If that belt becomes worn and defective, then it cannot properly run the pump that drains your dishwasher's tub. If your dishwasher uses a drive belt, examine it now. If it shows signs of wear, replace it.

A defective timer could interfere with a dishwasher's ability to drain properly. Test your dishwasher's timer mechanism. If it is faulty, replace it. Keep in mind that you can replace either the entire timer assembly or just the timer's motor.

The motor plays a key role in a dishwasher's ability to drain water. If your dishwasher's motor is not functioning properly, it will negatively affect the draining capability of your machine. Test your dishwasher's motor for continuity. If it fails the test, replace the motor.

In some models, a valve has to open in order for the water to drain out of the dishwasher. This valve is controlled by a solenoid, but it is the timer that decides when the valve should open. If your timer is working fine, check the drain valve and its solenoid. If need be, replace them.

I have a problem with my Asko D3350 Dishwasher, can you help? On startup the diswasher does its normal cycle and pumps excess water out and then fills the dishwasher with water to the correct level of...


Hi Tony,

I have the same machine (D3350) and almost the same problem.

Mine starts each cycle fine - pumps out - fills - rinses - pumps out tht first load and then does not fill again. If I manually fill with a bottle (about 2 litres) for each subsequent cycle then it washes as well as it ever did.

Seeing it fills once it cannot be the water supply, nor the solenoid that operate the water supply. So, my guess is the control panel.

Like you I would love to simply take advantage of the PC Upgradeable featurewshich seemed so attractive at the time of pruchase.

Dishwasher won't fill with water


Check the power supply to the water pump through a pocket electrical line tester or volt meter.

Poer reaches and the pump mot rotating, check the capacitor associated with the motor.

I have Kitchenaid kudk03itbl3 model dishwasher. It does not fill with water during cycle.


I will assume there is power to the unit and the water supply is on.

Simple things first and we can go from there.


Float valve is jammed.

Look inside the machine on the floor will be a small float valve. Looks like a small upside down cup. Lift it and clear anything from underneath.

The valve is a safety feature to stop the machine from over filling. If anything gets under the valve it will jam open and stop the machine.

Not working?


Water is pumped out by the machine via an internal pump located under the base. If it fails the water will collect until it trips the float valve. First scoop out all the water from the machine and run it again. If water comes in and it runs to the point it fills again and trips the float then either the pump or timer is faulty.

Pump check.

Remove the machine. It will be held in place by screws directly into the counter top. You may have to lower it to get it out. The front feet turn with a wrench to lower.

Turn off the water supply. Run the unit again until you get to the drain cycle.

Connect a test light or voltage tester to the terminals at the pump. Check for voltage at the pump. If you have voltage replace the pump. If no voltage the timer is faulty.

Timer problem?
Some can be replaced as a unit others are integral to the control panel. Turn style can be replaced. Touch control can not.

Dishwasher leaks from bottom left corner


If its just that corner check that it is level (if not leak could be somewhere else)

Then check your hoses and valves for holes or leaks (try putting some food dye water when running to see easier

Most likely a loose hose connector or hole in the rubber hose

Dishwasher Basics The main parts of a dishwasher are: Control mechanism
The control mechanism is located inside the door behind the control panel. Many units use a simple electro-mechanical system: a timer determines how long each part of the cycle lasts and activates the proper function at the proper time (such as the detergent dispenser, wash spray and draining functions). Units that are more expensive might have a computerized control system. Modern units also have a door latch that must be closed for the unit to run. Some also have child safety locks. Intake valve
This is where water from the home's water supply enters the dishwasher. The unit's pump doesn't pump the water into the basin – when the intake valve opens, water pressure drives the water into the unit. Pump
An electric motor powers the pump. During the pump cycle, the pump forces water up into the spray arms. During the drain cycle, the pump directs the water into the drain hose. The motor-pump assembly is mounted beneath the basin, in the center of the dishwasher. There are two main types of pump:
  • Reversible
    These pumps switch between pumping water to the spray arms and pumping water to the drain by reversing the direction of the motor. Reversible pumps are usually vertically mounted. dishwasher-11.jpg
    -->Reversible pump

  • Direct-drive
    The motor runs in one direction, so the direction of flow is switched from spray arms to drain by a solenoid that opens and closes the appropriate valves or switches one hose connection to another. Non-reversible pumps are usually horizontally mounted. dishwasher-12.jpg
    -->Direct-drive pump

Dishwashers can be installed in either a portable or a permanent configuration. Portable units have finished sides and top that can be used as a countertop. When not in use, the machine sits in place next to the wall. When it's time to run a cycle, the unit can be rolled on casters over to the sink, where it connects to the faucet and plugs into a nearby outlet. In a permanent installation, the dishwasher goes underneath the existing countertop and bolts into place. Hoses underneath the kitchen sink connect directly to the hot water line and the drain line, and the unit usually plugs in under the sink as well. Both types of installation require a 120-volt grounded line.

Will not pump out dirty water


Is it hooked to a garbage disp. If so make sure the knock out is out. Then if you can use a volt meter. take off the 2 screws at the bottom of the unit on the left side is your drain pump. take off the 2 wires put your meter on ac and put your leads on the wires then run it in a cxl cycle. (the cxl will depend on your unit you will press two buttons @ the same time and hold it it will light up 2(2min))
if you get 110 you have a bad pump........
