Bosch SHU4300 Water Fill Issue.

Recently came back from a weekend trip to discover dishwasher still running after 48 hours. Apparently there was some cloggage in the garbage disposal and that prevented the dishwasher from draining. Reset the Disposal and ran the dishwasher to discover that it was draining properly, but no longer filling with water. First step: Checked water lines and inlet valve for clear flow. Everything ok. With water valve removed from unit, applied 115VAC to test. Unit functioning. Reassembled valve and inlet. Still no water. Second step: Assumed then that an overheat may have caused a solder meltdown in the control unit which is common to these dishwashers. Discovered a hot spot on one of the solenoids in the control unit and a solder brake around a terminal. Re-soldierd terminal and reassembled unit. Still no water. Third step: Checking power to unit now....

Yup, that was it. Discoverd that the tray had some water in the float area where there is a bit deeper reservour than the rest of the tray, which was just damp. Didn't notice the float was switching the unit off until I got my hands under there are pushed the float down. Then it all made sense. No repair bills for me thankfully!

Re: Bosch SHU4300 Water Fill Issue.

Similar problem for us turned out to be water accumulating in the tray which set off the float switch.  I vacuumed the water out and function returned to normal.  However, we are now facing a repairman's assertion the clay in our well clogged the water inlet systems necessitating $285 in repair parts and labor.

Bosch Dishwasher drain mechanism starts itself a few hours after a completed cycle and won't stop. I reset the dishwasher, but it remains unusable for a few days. If I turn on the dishwasher, th

this could mean there is water leak and it collects at the base of the dishwasher leading to moisture detection circuit tripping. when you leave it for a few days the water dries up and trip is removed. check door seals for leak most likely at the base of the door. turn power off when working on dishwasher.

Check the drain line underneath the sink.
It should be suspended just below the counter top.
If it is too low,water from the sink will back fill into the dishwasher.
If the drain is OK,then the dishwasher water valve is defective.

My Bosch dishwasher is taking hours (at least 3 - maybe more) to complete a cycle. There is gummy, yucky stuff building up inside - sorta pinkish brownish. Could the water not be hot enough? A couple of...

if your on demand heater is one of the small ones that mounts under the sink, it will not flow enough water to fill your dishwasher. the dishwasher is waiting for the water level to fill before it starts washing. your bosch will heat its own water. hook it up to a cold line ahead of the water heater so that the fill valve is fed with full pressure. the residue sounds like detergent build up. when you get the water issue resolved, run a few cycles with no dishes and no detergent, on the highest temp setting. add a cup or two of white vinegar or dishwasher cleaner ( order online or get from an appliance repair store) through it. Dont forget your dishwasher has a filter in the bottom under the spray arm that needs to be cleaned periodically. if you dont clean it once a month it will get all kinds of nasty stuff built up in there.

No water in the dishwasher Bosch SHX43M02-48. We turned of the water and forgot to turn it back on and ran the dishwasher. Now the it will not let water in?

Hi, By the information you've supplied, I'd guess you burnt out the coil in the water/fill valve by running it without a water supply to the valve. Are there any other unusual symptom's or error codes ? i.e. drain pump running none stop ? Can you put water into the tub manually and run a rinse cycle without issue ? In any event the valve is pretty inexpensive, usually about $30 or so. The part # 425458 works on all bosch, thermador, gaggenau, and siemens dishwasher built since the early to mid 90's up to present day. Hope this was helpful to you. Thanks for visiting "fixya" today. Good luck. macmarkus :)

Bosch dishwasher: won't fill with water

The flood switch is tripped. This is located under the unit. Unplug or flip the breaker to the dishwasher, take off the black kick plate under the door, 2 screws, and you will see the white plastic "pan". The flood switch is located where you can't really see it but it is on the left hand side wall and is made of styrofoam. The best thing to do is to put some rags in the pan, this is not easy because there is little room to put them, and soak-up the water that has filled the pan. Eventually you will get enough water out that the float will deactivate the switch. What you hear "running" when you turn it on is actually the drain pump, it get activated when the flood switch is tripped.

Bosch SHX46A02Uc/21

it is likely a control module issue. I will take mine apart this weekend to verify what others have said: solder joint on circuitboard burns out from possible overheating, and DW doesnt go into rinse cycle. Try rinse and hold cycle to see if it stops on its own. mine does, but the other cycles which require the rinse to go to 156 degrees do not; the continue to run until I cancel and drain.

Bosh shu43c never stops running.

If you have a Bosch shu4300...check this site.

My issue was a heater fault and fixed the problem by resoldering a bad joint. Works fine once this was fixed.
