E5 Error Code / Pump not working

Make sure the pump button on the display board is pressed and the pump light is on.

NOTE: Normally, when the pump function is active and after the water is full, the pump will start to work again after approximately 10 mins. The unit will stop and restart to work when the water tank is full again. The pump operating noise is usually loud and the pump will not always continue to run. It will resume after a while and stop and then repeat to prevent overuse and overheating.
