Your tumble dryer needs to stand level and balance on its feet in order to function properly. Try rocking the appliance from side to side or back and forth. If it’s rocking a lot, your flooring may be uneven or there may be a problem with the adjustment of your appliance’s feet. Use a spirit level to check its balance.

To adjust dryer feet, reach under the appliance and find the lock nuts on the feet. Loosen them and turn the feet clockwise or anti-clockwise, until they’re firmly in contact with the floor. Tighten all lock nuts again by hand.

Most grundig tumble dryers feature reversible doors. Please check your user manual to see if your model has one. To reverse your tumble dryer’s door, follow the instructions in the manual. If you’re having trouble finding your manual, download it here using your product’s model number.
