Re: pumping out continuously!!!

Remove the lower kick panel by removing the 2 screws located just below the door hinge point. There should be a relay to the left side of the middle of the dishwasher. It looks like this sort of: --- / ! !----/ The arm looking part is the ! ! linkage that opens and close ------- the butterfly for draining. ! ! The other part is selinoid ! ! which is probably corroided ! ! or has overheated and is !-----! stuck. Remove the power to the unit and remove the 2 screws and the c clip holding the linkage on. disconnect the wires at the connection which is front right of the selinoid. Use some 3 in 1 oil if you don't have any electronic cleaner, and work the selinoid up and down. It is highly magnetized, so use some back arm. After it moves freely, re-install. That should do it. Now get in there and make me a pie ;)

Kitchenaid dishwasher kuds30ixssa has pump running but have no lights on control panel with door closed.

Did you have a power outage recently? They are notorious for damaging circuit boards--usually about 3-4 weeks after the power interruption strange things will either start happening or *not* happening with appliances due to damaged computer chips on the boards starting to fail. Your symptoms indicate either a blown user interface(push button panel) or a defective main control board(board with the brains on it) or both!

has the unit pumped out all the water? It may have a blocked waste hose.

Siemens Dishwasher Fault

there is a water level sensor in the bottom of the machine if this is faulty and stays on, this will indicate to the pump there is water still in the machine. I would check this sensor it might be blocked with debris and has blocked in the closed position. that woudl be the best start for this issue.

i hope this was useful.

Ldf6920st LG dishwasher. Pump runs continuously.

Continuous run of DW "drain pump" is common problem, with simple solution, and without "pulling" the DW!

Because the problem is likely a "stuck float riser assembly", a mechanical "glitch", from crud build up, I recommend trying one "might get lucky fix" first.

Look up above the door and remove (usually two) screws holding two metal "tabs" to bottom of wood counter. This should allow you to "rock" the unit a little. This might allow the float assembly to operate.

A. You have removed and cleaned the screens to the pump inlet and have manually added hot water which the pump removes but the pump just continues to run, even when you open the door? You should still be able to use controls to shut unit off. If not, you should be able to turn DW off at circuit breaker panel. Find and open the breaker any how, because "I'm sending you in!"

There are two sheet metal "plates" about 4 inches high, 24 inches wide below the door on Bosch (and others) dish washers. Remove both, usually they can just be carefully removed.

Lay with face on floor and use flashlight to look "up and into" the left bottom side of the DW. About a foot into the bottom left side of the unit look for a red or orange (usually) plastic rod about the size of a pencil rising vertically out of a thin plastic "tank". This is a "sump" of some sort (???) and the bottom of the rod is a "float". The top of the "pencil" activates a micro switch. Junk in "tank" or on micro switch stops rise of the rod which keeps pump running.

Carefully, manually lift the orange rod with a long wooden spoon. Several times. You should hear the micro switch click. Don't be sticking screwdrivers or anything metal in there. Even with the power off.

Turn breaker back on. This may solve most common problem in first five years for many brands of dish washers.

Good luck.

Bosch dishwasher shx46a06uc-30

the unit will try to complete the last command it was engage in before it went in the overfill safety mode. you must perform a cancel drain cycle to reset unit to default setting. Remember the drain cycle is 2 min and must be completed to reset main control. however if it went into a overfill status you have a leak and it generally comes from the pressure chamber on the lefthand side of unit where the water enters tub

Bosch SHU runs even when the door is open, what do i need?

Hi Jeffrey,

This depends what you mean by "runs". If the dishwasher continues with a wash cycle - i.e. circulating water - with the door open, the simple answer is that you have a defective door microswitch.

However, I suspect what you perceive to be the dishwasher running, is actually the drain pump running continuously. This happens when the anti-flood protection system has been activated and continues even when the door is opened. The simplest way to check is to open the door (while it's "running") and pour some water into the tub. If the water drains away immediately, this shows the drain pump is running and the anti-flood protection has been activated.

This may be due to water having leaked into the base of the dishwasher, but it could be as simple as a stuck or defective float-switch.

Please try the simple test above then post back for further assistance. If you're planning to investigate or repair this yourself, you're going to need a Torx T20 screwdriver and a multi-meter would be useful as well.

Regards, BElectric

I have a kitchenaid dishwasher modl # KUDIO01IL. Someone opened the door during a wash cycle and now the CLEAN LED is flashing. Tried pushing cancel and unplugging. No change. Any ideas/

Please check if the clean light is blinking 7 times. If yes then please reset the power to the dishwasher. After, 5 minutes check if you are still getting the same error. If yes, then it is a water heating fault. To resolve this error try pressing this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air Dry - High Temp - Air Dry.
If this doesn't work then its an issue with the heater circuit, door switch, wash pump not pumping the water past the heater efficiently or due to lack of water to heat. Please make sure that heater is not open circuited and is heating the water efficiently. If heater is fine then make sure water pressure is optimum and fill valve is working fine. Hope this helps... Please post back for further assistance.

I have a Bosh Logic dishwasher SGS65L12GB/04 The other day it got to 1 min left and would not stop pumping out water and continued even with the door open. After 5 mins playing around it started working...

Hi Jonathan,

Welcome to FixYa.

Your float may have got stuck or it's possible that you have water leaking into the bottom of the washer. In the bottom of the wash compartment, next to the drain you will find a plastic dome/mushroom (the float). You might need to rotate the bottom spray arm to see it.

Turn the washer on so that the pump starts to run, open the door and push down on the float. This should stop the pump running. When you let go of the float, if it rises back up on its own, then it's almost certain that you have water in the bottom of the washer. If this is the case please post back for further assistance. If the float stays down, then it may have simply got stuck.

Please try this simple test and post back with the results.

Bosch SGV43A03 DISHWASHER: pump drains all the time, even if reset!

Typically you could possibly have a leak in the base or sump which activates a little float switch. This in turn switches the drain pump on continuously and deactivates the programing cycle.Sort out the leak.
