The machine is in rented accomodation & the tenants never cleaned the filter. The filter has now been cleaned, it was thouroughly blocked, it still doesn’t empty.
I have ordered a new pump as I suspect it is burned out. Is this most likely the fault or should I check anything else ?
If you can’t actually hear the pump running, replacement is orobably your best bet. If you can hear it running, you have a blockage elsewhere, probably in the hose coming down to the filter.
