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.

Bush F721QB flashes start/stop lights after reassembly

The problem
After replacing the door seal on a Bush F721QB washing machine, the start and stop lights only flashed. The owner compared it with a working Bush SA127QW and found the front panels appeared identical.
Likely cause
The discussion most strongly supports a wiring or connector issue on the F721QB, likely related to reassembly after the door seal change. This is supported by the fact that both control boards reportedly worked in the SA127QW, and the SA127QW board also worked in the F721QB.
What fixed it
Recommended action was to re-check all board connections and wiring on the F721QB. The thread did not confirm an exact faulty wire, connector or completed repair.
Checks to try
  • Control board from the working Bush SA127QW was fitted to the Bush F721QB and the flashing stopped
  • The original F721QB board was tested in the SA127QW and reportedly worked fine
  • Connections and wires to the board on the F721QB were checked multiple times
Parts or tools mentioned
  • Door seal
  • Mainboard / control board

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

Hello Dave. If a part doesn't work in one machine but it does in another then it's highly likely that it is the connections or wiring, especially if a replacement part works okay as you described. I honestly can't think of any other explanation.
