Hi,

I have a blown suppressor on my Bosch washing machine. Problem is I am in rural France so getting a new part is going to take a while. I assume I can bypass the suppressor by connecting the input connectors direct to the output? Appreciate this is not ideal but it will get the machine up and running until the new part arrives.

Thanks

Paul

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 washing machine with blown mains suppressor

The problem
The washing machine was reported to have a blown mains suppressor. The user asked whether the suppressor could be bypassed temporarily by joining the input and output connections directly until a replacement part arrived.
Likely cause
A failed mains suppressor was stated by the user and accepted as the basis of the reply, but no diagnostic evidence beyond that was provided.
What fixed it
The accepted reply said that, if it is definitely the suppressor that has failed and the bypass is done correctly on a simple live/neutral in and live/neutral out suppressor, the machine should operate without it. The longer-term action implied was to fit the new suppressor once available. The thread does not document a completed repair or confirmed result.
Checks to try
  • Confirmed whether the suppressor was definitely the failed component
  • Confirmed the suppressor was a simple type with live and neutral in, and live and neutral out

Safety: Do not bypass a safety-related or mains component based on forum advice alone. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello Paul. If it is definitely the suppressor that is blown, and you definitely know how to bypass it properly then yes, a correctly bypassed suppressor should allow the washing machine to work. (assuming it is a simple suppressor with live and neutral in and live and neutral out). The suppressors function is to prevent electrical interference in other products such as TVs and radios and is a legal requirement because this interference can occur at neighbouring houses.
