⚠ Safety note: This guide involves working with plumbing. If you're not completely sure about every step, stop and call a licensed professional. Before you start, always switch off the power at the breaker or close the main water/gas valve.
1 Prepare for safe work
Ventilate the room, put on gloves, and test the cleaner on a hidden area first. Protect children, pets, textiles, and sensitive surfaces.
⚠ Warning: Never mix bleach with vinegar, acids, ammonia, or other cleaners. The mixture can release toxic gases.
2 Determine the condition and cause
Turn off the machine, pull out the drawer according to the instructions, and photograph the position of the softener and liquid detergent insert.
3 Perform the key check
Soak the removable parts in warm soapy water, clean the channels with a soft brush, and wipe the housing without getting the electronics wet.
4 Do the repair or maintenance
Rinse, dry completely, and return the parts. Use the correct dose of detergent and leave the drawer slightly open after washing.
? Tip: Photograph the initial state and change only one thing at a time. This makes it easier to determine what really solved the problem.
5 Test the result
Remove product residue according to the label, dry the surface, and inspect the result in daylight. If the problem returns quickly, find the source of moisture, dirt, or malfunction.
