Important regarding heat pumps for dishwashers

When your dishwasher is manufactured with a heat pump (pump motor combined with heating element), pay particular attention to the following, which may cause the heat pump to malfunction:

1. Too much detergent: If you use all-in-one-tablets, you should only use half a tablet to avoid detergent residue on the heating element. Alternatively, you can use gel or smaller tablets.
2. Detergent tablets with foil: If you are using dishwasher tablets with soluble film, avoid short and cold programmes, as the foil will not dissolve. Instead, the foil will settle on the heating element.
3. Descaling: If the correct amount of salt is used, descaling will not be necessary. However, since it can be difficult to know whether the salt dosage is set 100% correctly, it can still be a good idea to descale the dishwasher occasionally. This will ensure that limescale does not build up on the heating element.

Once the heating element has broken, there is no other solution but to replace the entire heat pump. However, once the heat pump is replaced, you should pay particular attention to the above.
