Thetford Flush Control PCB (SN) for C250 Toilet

Thetford's genuine SN-spec flush control circuit board for the C250 range of cassette toilets. It takes the signal from the flush button and switches power to the water pump. If your flush stops responding, runs continuously or behaves erratically while the pump and switch test fine, this board is the most likely cause.

• Q: What does the 'SN' version mean?
  A: SN refers to the standard/basic C250 control, typically used with a single flush button, as opposed to the CS or CW electronic variants which have different control boards.
• Q: My flush pump won't run, is this the fix?
  A: If the pump runs fine when tested directly but not via the flush button, this control board is the most common cause of failure.
• Q: Does this fit the C260 as well as the C250?
  A: Yes, this board is shared across the C250S, C250CS, C250CWE and C260 cassette toilets.
• Q: Do I need any tools to fit it?
  A: It's a straightforward swap for the existing board behind the toilet's control housing, a screwdriver is normally all that's needed, but disconnect power first.
