Replacing the flex in a hardwired mains filter

I've got a Hotpoint WD420P, the mains lead has gone faulty so I've done a temporary replacement with replacement flex and a suitably rated chocolate block onto the last couple of inches of good flex. The machine is still out from its space in the kitchen as I'd not be happy leaving that 'bodge' as a permanent repair :)

Unfortunately the filter does not have spade terminals on the incoming side, the flex goes straight in. I had a half-hearted attempt at opening it, is there a trick to getting these open or do I need to spend £30 on a complete filter and mains lead? (eSpares item ES800896).

Thanks for any advice :)

Solution Summary

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

Hotpoint WD420P hardwired mains filter with faulty mains lead

The problem
The mains lead on a Hotpoint WD420P washing machine was faulty. The owner found the mains filter/suppressor had the incoming lead hardwired into it rather than using spade terminals, and asked whether the filter could be opened to replace just the flex or whether the complete filter and lead assembly was needed.
Likely cause
The discussion supports that the mains lead and suppressor are supplied as one combined part, so the flex was not intended to be replaced separately at the filter.
What fixed it
The accepted reply stated that the mains lead and suppressor appear to come as one part. A temporary joined cable using a proper 13 amp connector was suggested as acceptable if secured and kept dry, but no permanent repair was confirmed. The original poster then said they had found second-hand filters for about £10, but did not confirm fitting one.
Checks to try
  • Owner observed the incoming flex goes straight into the mains filter rather than onto spade terminals.
  • Owner had a brief attempt at opening the filter.
  • Second-hand replacement filters were found for around £10.
  • A complete filter and mains lead assembly was identified as eSpares item ES800896.
Parts or tools mentioned
  • Mains filter / suppressor with mains lead assembly
  • 13 amp connector
  • Insulation tape
  • Replacement flex
  • Chocolate block
  • Second-hand filter

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

Yes it looks like the mains lead and suppressor come as one part. Another money saving practice. If you use a proper 13 amp connector and fit it well making sure the connection can’t get pulled or fall on the floor where it could get wet I don’t see any reason why is shouldn’t be ok. I’d wrap it in insulation tape too.

After all, the reason these connectors are made is to join two 13 amp cables together. If concerned you can buy really good quality connectors made with hard plastic.

Thanks for your reply Andy. I will take a look at connectors, however since posting I have noticed lots of 2nd hand filters on eBay for around £10 which is much more palatable :)
