Hotpoint dishwasher.

[bzz67]

LFS114K UK semi integrated dishwasher.
Called out to this machine for noise and no wash. Impeller was off in the circulating pump, changed the pump and now it appears to error out after around 90 seconds of filling. We changed the flow meter assy and still not working. There is continuity on wiring from flow meter to module. Over fill pressure switch is not the problem. After the 90 seconds of filling (water level just below salt container nut, seems ok) the machine goes into drain with the wash light, end light and salt light flashing.
There seems to be very little info on this one. Appears to be a module fault but this fault wasn’t there when we started the job.
Any help would be great.

Could be timing out on fill, have you checked inlet pipes and water presure?

LED 1 & 3 Pressure Switch
The machine has filled with 2.5 litres of water but the pressure switch is still in the empty position.
• Check the filter or sump is not blocked.
• Check the pressure switch is not stuck in the empty position (contacts 11-12) or the
pressure chamber or air tube are either blocked, unattached or split.
• Check the wash pump is circulating the water.
• Check the wiring to the pressure switch.
• Check the edge connector blocks on the pressure switch and module card.
• Check the outlet hose is not too low causing the machine to siphon.
• Aborts the cycle and energises the drain pump.

Re: Hotpoint dishwasher.

Thanks for your help. Found the fault in the pressure switch. when we changed the circulation pump we lent the machine over, water must have got down the pressure tube and into the the pressure switch upsetting the pressure at which it clicked at, worked ok when i blew into it.took it apart, dried it out and now its fine. a good one for all of us to remember.
