Bosch nexxt 500 series washer problem

I was told by my local repair shop that my washer needed a new drain pump. I put that pump in but the washer still will not drain.

I entered diagnostic mode and under P:15 (which should be the command to drain and spin) I get a code of 88

I need to know what that code means.

Thank you for your time

Jay: Here is the URL address to Searspartsdirect.com and the only model shown is WFMC530Cuc-13. I would call Searspartsdirect and have them look up the part # for the control board by your model number. Based on the lack of Nuetral to the drain pump, the control board is faulty. The control board controls the hot side and the nuetral side to the drain pump.

After bringing up the P:15 setting and pressing start, that's when the 88 or 63 show up flashing at me. I did manage to check the voltage at the motor leads and I get 120 hot to ground but only about 40 volts hot to neutral. I don't see any damage to the wires and there are no signs of a break in the wire that I can see.

Model number is also confusing as I can't seem to find it online anywhere. WFMC530CUC/16

Thank you for your question and I understand your concern.

If the new drain pump is not running and there are no loose wire connections in the drain pump circuit, the control board is most likely faulty. 

 

I would check voltage output to drain pump when it’s energized. If no voltage, replace faulty control module.



NOTE: I do not recommend measuring the voltage supply at the drain pump unless you have experience and feel safe and confident in doing so; otherwise I recommend calling a service technician to diagnose and repair your washer.

The #88 is not a code and it is not listed anywhere in the service manual.  When you enter the test program and advance to the drain pump test, P15 should display and Start/Pause should be flashing. It also does not make reference to error or #63 when you pulled the pressure switch hose off.

Since you replaced the drain pump, the control module is most likely faulty if the drain pump is not getting the voltage supply.

 I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post along with the model number of the washer.

 If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link:

Sears Home Services.

I took the hose off the pressure switch, and now the code reads 63. I also tested the switch by blowing gently into it and I could hear it switching. I put the hose back on and no luck.
