Simpson Eziset 550 wont start 3 flashing lights

[Cylon]

Simpson eziset 550 washing machine wont start, I press power on then the start button and beeping alarm starts with the three water temp lights flashing, I have replaced the cpu with a new exchange unit, it programs ok.
On spin It just sits and waits. checked for all the normal faults. Any ideas anyone

I can’t claim to know the product, but design convention on most washers will prevent the machine from filling if the pump is out of circuit.

Found cause of lights, needs lid on (magnetic switch)
Really dumbing down today
However this did not fix it.

Pump runs ok on its own, checked every valve and switch and motor on it now.
result is Zilch, can only suspect I got issued a dud exchange cpu

All 4 Wash Leds Flashing ?
Means Out Balance
Check OOB knock off lever & Microswitch for OOB (Microswitch is normally closed) As opposed to LID Switch
Fairly rare that PCB Goes Bung

Re: Simpson Eziset 550 wont start 3 flashing lights

No oob problem. in fact no alarms of any kind.
I Just fitted another cpu that I ordered. This one is definitley faulty, it wont accept any programming inputs at all, and has a bad AC plug socket contact on the board that cuts in and out, so I guess this goes back too
Contact works fine on the original one
Still leaves me in same dumbfounded mess, with the original cpu. Machine sitting waiting for input of some kind, In progress light is on but no progress to anything. Spin or wash. (pressure s/w activated)
I have tested the wiring loom. test run the motors and and valves, all work ok independantly
I have noticed that I am being supplied with differing model and version numbers than originally fitted.

I am being assured by the parts supplier that Once reprogrammed they should should work. Maybe Not methinks
