Daikin EUWA50 Chiller

[piston broke]

Has anyone worked on an EUWA50 chiller?

I had a high pressure problem which I sorted out but then the oil switch light started showing without the chiller even running. The wiring circuit was extremely difficult to follow. Couldn't get the thing to run.

Returned next day to start affresh. Switched on and it worked first time.

What's going on?

I haven't worked on one of these chillers, but the problem you described sounds like it is wiring related.

Did the oil safety trip after the high pressure switch tripped?

If so, the opening of the high pressure switch must have energized the resistance heater in the oil safety switch.

That should be fun to sort out it that's the case.
