Bosch SHU43C Dishwasher

No water coming in - changed out the water valve, no change - assume it's the float mechanism - your response to another writer with the exact problem was "Float switch is in the flood position" how do I see if that is the case and how do I resolve it if that is the problem. Do I need to back the unit out of it's secured position. If so what do I need to watch out for / be aware of .
Thanks

Had the same problem. The float switch was stuck in the filled position. Removed left side panel to reval fill and flood safety mechanism. Inspection revealed sludge ( soap scum?) caused float to stick in flood/full position. The drain pump just kept trying to empty sump and no water came. Dis-assembled float assembly, cleaned out sludge, re-assembled unit and let her rip.

Is there no water coming in( hear no water at all) or no water NOT staying in ( drain motor running) ... the float switch is a safety to keep the dishwasher from flooding ...turns on the drain motor as soon as the door is closed..

I could check the control and see if you have power to the water valve.. maybe a control problem if no power..

Dishwasher will not fill with water when turned on


Hi and welcome to FixYa, I am Kelly
The following steps require using electrical power. You assume all responsibility / risk for any mis-fortunes cause by working on this dishwasher with power applied.

The first step will require using a meter on the water valve solenoid teminals.
- Remove all power.
- Remove the lower toe / kick panel(s).
- Locate the main water supply line and follow that to the inlet water valve.
- Slide the connector(s) off of the solenoid and read resistance on meter scale R x 1 or R x 10. You should read a low resistance. If you do not read any resistance the inlet water valve has failed.
If you do read resistance you must check switch the meter to AC voltage and apply power and read for AC voltage on the teminals of the wire harness.
- Start a reular wash cycle to where the unit should be filing with water.
it SHOULD read 120 VAC.
If you have no power at the connector teminals
- Check the float switch plastic FLOAT. If the float is stuck in the UP position due to food particulate on the FLOAT stem you willnot have power to the inlet water valve solenoid.
If you have power to inlet water valve solenoid and it is buzzing / humming but you get no water there is debris in the main water supply line. You wil have to shut off the water supply and clean out the inlet of the water valve.

The inlet water valve replaement part is here:

This is what the float looks like:
http://www.appliancepartspros.com/Appliance-Parts/bosch-float-item-number-ap2802399.aspx

This is the level switch assembly:
http://www.appliancepartspros.com/Appliance-Parts/bosch-level-switch-assembly-item-number-ap2802390.aspx

This is the actual Float switch: (3 terminal)
http://www.appliancepartspros.com/Appliance-Parts/bosch-float-switch--3-terminal--item-number-ap2802373.aspx POWER to the inlet water valve solenoid comes from this switch.

Check for s stuck float... and that the level switch is actuated as the float id lifed gently up and down. If you do not hear a micro-switch click the switch is bad. If the float is hard to move... clean it as best you can so that it moves freely up and down.

One of the above is causing your problem.

Thanks for choosing FixYa,

Dishwasher will not fill have changed the inlet valve but still not filling.


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.

Our Bosch SHU43C Built-in Dishwasher sticks in the drying cycle.


I have the same dishwasher and started experiencing the same problem last week. It is now fixed (at least for the moment). Here's what I did first. I checked the drain pan under the machine for water(none), the heater for continuity(okay), the float for binding(none), and the float switch for proper functioning(okay). I tried turning the ckt breaker off for a couple of hours to see if that would reset the control module(no effect). I then dissasembled the front door and removed the control module. I had previously read about the common problem of a cold solder joint on the heater relay pin on the control board. My heater was working and the joint looked good but I resoldered it anyway. I reassembled everything and it worked perfectly! My conclusion is that it was either a cold solder joint that was somehow causing the problem or a connector issue that got resolved during my disassembly/reassembly. Hope this helps.

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!

Make sure you have water coming to the dishwasher. Next check your dishwasher float. Make sure it is not sticking. If not you could have a problem with your fill valve. Check for voltage at the fill valve if you have 120V then you need a valve the solenoid is defective. Replace it.

Bought the display unit and water will not work.


hi there the low humming noise that you are getting sounds like the fill valve, this could be due to you perhaps not turning the water back on after fitting the new dishwasher or the fill hose being kinked when the dishwasher was put back ,hope this is of some help to you.
