the presure switch , obviously is a switch that measures pressure

theres a bottle on the side of the sumphose whih then has a thin tube which then leads to the switch
as the machine fills with water, air is forced up the tube and as a suitable fill level is met, the switch activates, and the valve is switched off

now.. possible cures?

1 > sometjhing stuck in the pump.. taking the sump of the rear of the machine will confirm this

2 > hole in the pressure hose

3 > faulty pressure switch itself

4 > faulty control board

5 > machine syphoning… this isnt uncommon in machines that have been sat for a while.. questions are – does it fill with water? doea the water level go up the glass? does it fill with water and never seem to fill up?

that would involve adjustment of the waste hose… is it in a stand pipe? is it pushed too far down? the end of the hose should only be placed 2-3 inches in the stand pipe, not pushed to the bottom

many questions, numerous potential cures

but if your gonna look, unplug and make sure you work cleanly and safely

good luck

theres a memo about that.. why cant i find it?

[helo_75]

the pumps always run at the start of every program, thats normal

quite often, its a faulty valve coil?

not impossible pcb is faulty though, ive had that too

[helo_75]

is it hot snd cold fill?
if it is it sounds like the hot valve is trying to top the machine up after its second fill

check the water supply is good, and the filter in the valve is not blocked

it does sound like a water supply problem

sorry if my previous post was a little abrupt

i apologise, i was in a rush…

however, i must point out that the fact that the heater was indeed wet, and that needs investigating

theres probably a blockage in th e cahannel from the condenser chamber to the pump, leading to water overspilling onto the fan and wetting the heater

the drain hole is situated in the pump chamber, and is on the bottom left of the the housing, under the pump… its worth pushing something through it to make sure its clear

good luck

just put a heater on it

[helo_75]

thought so

ive had a few of them ove written off, after countless stats and compressors

[helo_75]

i dont care either…… glad to be of service

[helo_75]

grrr, spot the guy whos half asleep.. your right, sorry. e20 is a pump fault of some sort

[helo_75]

you should have email 🙂

[helo_75]

if you want the bleep back, hold in the middle 2 buttons for 3 seconds

and every e20 ive beeen to has been the green valve coil on the cold valve 🙂

[helo_75]

but whats the cure? is it a write off?

[helo_75]

there very erratic, it has to be said

needs a pcb im afraid
