Hi Jeff - Yes I discovered there is a float with a magnet in it which
operates a reed switch and in addition there was a small fruit pip
stuck in the float chamber so I was convinced this would be the problem
- but alas no - the reed switch works, but the problem is still there.
The full model designation is GSF4872TW-WS or the model number 8546 372
Thanks in advance for any other ideas, Mark...
