E04 error: Swimming pool heat pump

[Sideshow Bob]

Any one had this? It happens once in a while but next day it generally sorts out itself. I am not sure if there is anything I can do to fix it without calling technician. Problem with calling technician is that error code comes literally once in 3-4 months (and pump stops working that day) so by the time they arrive, problem won't exist.

I googled and "The E04 code typically means there's a problem with the outdoor temperature sensor or wiring."

I had managed to solve it back then by cleaning pool pump basket. Some leaf litter must have been clogging it although it wasn't that bad really. I had seen it much worse before and never had this error before.

I had same problem again today so thought I would update the thread in case it helps someone. I put up a reminder to clean up this every fortnight or so now.
