My bosch series 2 washer trips after about 15 seconds of filling with water but when I run a spin cycle to empty the water it works fine. (I had a problem with it not pumping out the water but that was because of some plastic stuck in one of the pipes). I am thinking heating element?

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Bosch Series 2 trips the RCD shortly after filling

The problem
A Bosch Series 2 washing machine trips the RCD about 15-20 seconds after it starts filling with water. It will run an emptying and spin cycle without tripping. A previous drain fault was traced to plastic stuck in a pipe and was cleared.
Likely cause
The discussion suggests an electrical insulation fault. Because the machine does not trip on emptying/spin, the motor and pump were considered less likely. As it also trips on rinse and spin after filling, the strongest supported possibility is water leaking onto an electrical component rather than a heater fault being confirmed.
What fixed it
No confirmed repair was reported. The recommended action was specialist fault-finding for an insulation fault using appropriate test equipment. Further diagnosis should be carried out by a suitably qualified appliance engineer.
Checks to try
  • Tested emptying and spin cycle, which worked without tripping
  • Tested rinse and spin cycle, which filled and then tripped the RCD after about 20 seconds
  • Previous blockage in a pipe was removed to restore draining
Parts or tools mentioned
  • specialist insulation test meter

Safety: Do not continue using a washing machine that is tripping the RCD. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi.

I have not tested a rinse and spin cycle just an emptying and spin cycle will try the rinse and spin and get back to you

I'm trying to eliminate the possibility of water somehow running onto electrics causing fusing. If it only trips on wash cycle and not rinse or spin then heater is definitely a suspect Washing Machine Tripping or Fusing The Electrics

As my link in my last reply advises, tripping the electrics is normally a fault you need a specialist insulation test meter for. However, if it doesn't trip on a spin cycle it implies there's nothing wrong with the motor or pump. If it only trips on wash it is commonly the heating element, but if it also trips on rinses it implies water is leaking onto something possibly.
