Bosch Dishwasher won't fill with water

Bosch Dishwasher SHU42L, SHE43C We push the on/off button, lights come on we hear the motor but water does not come in. This just suddenly started happening, used to work just fine. Manuel doesn't say anything about this problem. The first time this happened we tried pressing the two buttons to cancel drain and that worked. Now however that does nothing. Have already looked in the drain and cleaned it out, doesn't seem to have anything wrong there. Any ideas? Thanks

    I've read this about a float before and I don't know where that is or see a float of any kind? Also don't know where this valve is you're talking about, and how the heck do we test for voltage? We're handy or savvy about electronics.. Please note the model number I typed did not match perfectly with the product # choice available on the question form.

    Any other ideas or advice?

  • dishesdirty Jan 24, 2008

    I advice we received was not helpful. We do not see a float of any kind. The lights still come on so I do not think it is electrical. Please advice if this is something a lay person can fix or if we need to hire someone. Thank you.

Certainly *sounds* like the float is stuck in the over filled position
or possible a bad float switch, if the float is stuck in the up or full position, the d/w will not fill with water and the drain motor will often run all the time

    Start at the valve-- the water inlet solenoid valve behind the kickplate-- and see if it's getting voltage when the dishwasher should be filling. If not, then we have a control problem to troubleshoot. If you have voltage at the valve, then the valve is bad.

    Keep the objective mind: you're trying to measure an event where the valve is getting 120vac but fails to release water or, conversely, where the valve is NOT getting 120vac when, in fact, it should be. One way of accomplishing this is by testing at the valve. Another way is by testing at the control board. If you do NOT see 120vac at the time when water should be entering the basin, the control board is bad. If you DO see 120vac at the control board but not water, what do we conclude, given that the water inlet valve has already been replaced?

Bosch SHE44C06UC/22 won't fill with water even though you hear water running somewhere.


Check to make sure there is no residual water underneath the unit, they have a flood sensor and if it is picking up water in the motor area it won;t run.

Why does drain motor start when pushing the start button on the door before the door is closed?


It's almost certainly the float switch in the bottom of the machine. In the bottom is a polystyrene 'float' that is either active due to water in the bottom or is faulty. Tip your machine to the side and remove water and try again, bridge or replace switch is also an option

Bosch dishwasher SHE46C06UC won't fill with water


Check water inlet. Check for kinks in hose. Check the inline strainer in the fill solenoid. You say it makes an attempt to fill, is this because you can hear water trickling? If so I would suggest get to g the fill solenoid replaced as it may be blocked or not opening fully

Bosch SHX46AO60C/30 won't fill with water. Have check water under sink - it is on. Motor will run, but no water. Have tried all cycles.


Hi

When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.

Year old Bosch SHU33A0UC won't start. Lights on


Light's on mean you have power.

Initiate the self test program by doing the following -

To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on
by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press
ON/OFF button.
To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each
program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended
and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault – note circulation motor stops shortly after it started
during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain
where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150ºF) and water won’t stop
circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end
shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Let me know what you figure out. I can repair these boards most of the time.

Dishwasher won't go through it's cycles.


Remove the bottom panel and check the float switch, it is probably stuck in the up position.

Bosch SHU43C installed in 2003


My Bosch SHU43C had the same exact problem. I found the below solution on this site. Perhaps you already seen it.

My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!
