Having problems with your Bosch Dishwashers ?

Drain pump runs all the time.

\015 I have a Thermador DW245UW/06 Model dishwasher. The drain pump will run all the time,you have to turn the washer off for it to stop. Have done Troubleshooting and found the control Module showing the Heater relay terminal burn on the pc board, made the repair per manual but still have same trouble with drain pump. On the troubleshooting have checked the float switch and diaphragm plus the base float switch, all checks Good. Did the test program and had two codes ,Aqua sensor and Heating fault. Could this case the pump to run or it is due to a bad control module\015

Answers :

Hi.

The problem is either a wiring contact or a defective control module. Testing is done reading volts at pump contacts and at control board terminals.
This kind of test is a bit complicate, it must be done with power on and with door switch jumped , with the tech manually advancing the timer. For safety reason full testing must be done by technician.

Regards.
Hi,

This means that there is water below the tub inside the lower base pan. To access you will actually need to uninstall the dishwasher and remove the left side panel. Use a towel or rag (make sure the power is disconnected to the dishwasher) and soak up all the water in the base pan. Run a cycle with all the water gone and it should be OK, but if water re-enters the base panel and creates the issue yet again, you will need to look for a leak under the tub somewhere.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

GLD4050 DW won't pump out at any time during wash cycle. Removed lower arm, screen, etc. and washed and cleaned out everything. Removed drain hose and cleaned it out. Reinstalled and ran again. At no time during he cycle does the water pump out. HOWEVER, if I put my hand on the drain pump I can feel and hear the pump running as usual at the right times in the cycle. What else could be preventing the pump out? Thanks!

Kitchen Aid Dishwasher KUDR24SEBLO does not drain 100%. I have removed the drain hose and chcked the sink P-Trap, [it drains thru the garbage disposer]. Unit is 10 years old, otherwise works fine.

My brandt VF300 doesn't drain at the end of wash cycles. If you run the soak programme it drains fine. Some time ago the door was adjusted by an engineer, when he arrived he pressed some buttons which then drained the unit immediately, I have forgotten which buttons! Is there anything I can do to reset the thing, given it drains on soak I am doubtful the drain pump has broken ir is blocked?
