Heat pump dryers are becoming increasingly popular because they save electricity. however, like other electrical appliances, they require regular cleaning or maintenance. Here you can read which malfunctions heat pump dryers are particularly prone to.
Possible malfunctions with the heat pump dryer
A heat pump dryer is a relatively complex device that can be subject to certain malfunctions.
It can be:
- The dryer does not dry properly
- The level indicator of the water tank is incorrect
- The dryer heating does not work
- Drum does not move
Poor drying: Clean the fluff filter and condenser
You buy a heat pump dryer because you think that it is financially worthwhile compared to other dryers. If it does not dry in the prescribed time, the process is repeated and the dryer then requires more energy than expected.
The problem is usually with the lint filter. If it is clogged, the sensor that measures the moisture content of the laundry is blocked. Possibly. the drying process is even canceled. You should therefore clean the lint filter after every drying process. Incidentally, this is also necessary because of the risk of fire. The dry fibers can catch fire.
You should also clean the consensator from time to time. It is located under the dryer behind a cover.
Condensation: clean the fluff sump
In addition to the lint filter, a heat pump dryer has a lint sump at the bottom of the device. This is where the condensation water flows in before it is directed into the collecting container. Fibers also tend to collect in the fluff sump. Then the device reports that the water tank is full.
Heating: replace thermostats
If the dryer does not warm up, it does not immediately mean that it is defective. Or maybe it's just the thermostats. They can be exchanged.
Drum: Check V-belt
The laundry dries in the dryer, among other things by being spun around in the drum. If the drum stops rotating, the laundry stays wet.
Open the dryer cover and check that the V-belt that drives the drum is properly seated. Maybe it even cracked. Then replace it.
Or maybe the tension pulley is broken. An indication of this is that the drum is difficult to move.
