evening all,
looked at this today with f4/f1 errors displayed and water in sump.emptied by hand and checked drain pump.propellor was broken and very worn only one section left .fitted a new pump and tried d/w pumped out and started to fill.then f1 Ntc fault.
is the ntc part of the sump level switch?why would these 2 faults appear together?
thanks
Niall
finally got part and fitted it
job done.
this part fits where the old type vacuum level switch fits in the sump.not exactly sure how it controls the water level as it is solid plastic but has lenses, but it also acts as the ntc as it has a probe for temp.
