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 Maxx Classic trips electrics during wash cycle

The problem
The Bosch Maxx Classic would spin and pump water in and out normally, but after a few minutes on the wash cycle it shorted out/tripped the electrics.
Likely cause
The strongest diagnosis in the discussion was a faulty heating element causing an insulation fault, because the machine reportedly did not trip on spin and was said to trip during the wash cycle. The exact fault was not confirmed.
What fixed it
The accepted advice was that the heating element should be checked first, but this requires an insulation/installation test meter and proper diagnosis by an engineer. A visual inspection with the machine disconnected from the mains was suggested only to look for any obvious loose or shorting wires. No repair was carried out. The owner replaced the machine and took the old one for recycling.
Checks to try
  • Confirmed it spins normally
  • Confirmed it pumps water in and out
  • Observed that it trips after a few minutes on wash cycle
  • Advised to double check whether it also trips on rinses
  • Suggested visual check for loose or shorting wires with the appliance disconnected from the mains
Parts or tools mentioned
  • Heating element
  • Insulation test meter
  • Installation test meter

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

This is a very difficult fault to troubleshoot without an insulation test meter. If it only fuses or trips when washing though number 1 suspect is the heating element Washing Machine Tripping or Fusing Electrics

Thankyou for that. It has only ever been used on a cold wash and the hot water tap has never been connected. So does that narrow down the problem? I really appreciate your input as we are on pensions.

No Vicki, the hot tap is nothing to do with the heater. The heating element will always be used even if you have a hot water tap. If a washing machine doesn't trip on spin, or on rinses (double check this) - but it trips when it is on a wash cycle then the first thing that needs checking is the heating element. Unfortunately it can only be checked with an installation test meter which costs hundreds of pounds. So you would have to get proper engineering to check that. The only thing you could possibly do yourselves is to take off the back panel, disconnect the washing machine from the mains and just have a good look round in case you are lucky enough to find something like a wire that has come off and is shorting out. This is unlikely but if necessary you could give it a try.

It all got too hard as we live out in the country with no close by technicians. Thankyou so much for your input.

I ended up getting a new machine and taking the old one to a recycle depot.

Thanks for the update Vicki. It's a shame as it might only have been the heating element. If there are no local engineers you should always be able to get the manufacturer to repair it. But these days even replacing just the element can easily cost over £100.
