whirlpool awz 8469 condens type, didn't heat up or shortly and then only ventilates. Solved by putting some water in the place where the watercollectorreservoir was, then put the waterreservoir back in. The inputed water runs down to the waterpomp and pomps it back in the reservoir above. Somehow this makes everything work again!! It heats up whole the time.
