Hi, Bought the tub last June and it worked fine. Stored in dry garage for winter. Refilled it and heated it up, it did seem to take longer to heat up this time. Used it once, fine. Used it again and after use my partner inadvertently switched it off at the plug. Switched on again but in the morning it was off. I tried switching on and it starts but cuts out after 15 seconds. I've cleaned filter and inside filter housing and flushed it through but it has not solved the problem. Left it for several hours, tried again, still tripping off. Any ideas please? Is there a reset button on the heater at all?
