Griff G. for Model Number KUISPR15HB6 I narrowed it down to the optional drain pump. The water supply relay closes and the water supply starts entering. Then in about 1 minute the drain pump starts then shuts off power to the rest of the unit (board, interior light, etc. from power supply inside unit) Then in about another minute, power returns and the water supply relay closes and the water supply starts entering again. This continues forever. BUT.....I unplugged the drain pump from the internal 120v supply and connected it to the household wall receptacle. Now I'm making ice. The drain pump still comes on and drains but cycles about every minute even when the unit is in OFF mode. Current QUESTIONS... 1) What is in that power supply that supplies 120vac and 7 amps to the drain pump? 2) What did I bypass besides the on/off switch? 3) Does the pump suppose to continue to cycle every minute or so when in ON position? 4) Do I need the entire pump or are there parts that can be replaced within the pump or power supply box?
Answer Hello Griff. When the drain pump turns on, it shuts the unit off because of the amp rating. If the pump continues to come on, you either have a water leak inside the tub of the unit, or the float in the pump is bad. Look for water splashing outside the bin into the bottom. If it does, a little turns on the pump alot. If there are no leaks, you will need to replace the drain pump assembly. Hope this helps. Read More...
