This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Washing machine trips electrics on 1000/1200 spin but not 800
- The problem
- The washing machine trips the electrics on 1000 and 1200 spin speeds, but runs normally on 800 spin. The owner had removed the motor and found some chewed plastic debris inside, which was cleaned out, but no fault was confirmed.
- Likely cause
- The accepted reply suggests a probable insulation fault, a motor fault such as excessive sparking, something shorting when the drum moves more on high-speed spin, or a leak that worsens during faster spin and shorts a component. The exact cause was not confirmed.
- What fixed it
- Recommended action was to check the machine's insulation with a proper insulation test meter, then carefully examine and observe the machine for signs of excessive motor sparking, movement-related shorting, or leaking during high-speed spin. No confirmed DIY repair was documented.
- Checks to try
- Motor removed and inspected; chewed plastic debris found and cleaned out
- Machine behaviour compared at 800 spin versus 1000/1200 spin
- Advised to check insulation with a proper insulation test meter
- Advised to observe for excessive motor sparking
- Advised to inspect for shorting caused by drum movement on faster spins
- Advised to inspect for leaks worsening on faster spins
- Parts or tools mentioned
- multitester
- insulation test meter
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

This article explains basic fault finding and the limitations for diy fault finding on fusing or tripping washing machines
If it only trips on the fast spins but not on 800 spin I'd suspect either the motor (is it sparking excessively just before it trips?) or something shorting out when the drum bounces about on faster spins or even a leak getting worse on faster spins and shorting something. The first thing that needs checking is the insulation but as my article points out you can't do that without a proper insulation test meter. After that it's about carefully examining the machine and observing it.
