Upper arm of the dishwasher does not turn

If the upper arm of the dishwasher stops rotating, the typical causes are dirty nozzles or feeds. In rarer cases, but also possible, is a mechanical defect. Gaskets, pump and bearings can impair or prevent this function.

Clean after disassembly

If the upper spray arm does not turn or does not turn sufficiently, first check all the cleaning nozzles and the thrusters on the two head ends. All openings only work if they are clean and clean. In order to reliably rid the individual holes of greasy soiling, needles are a good aid.

In the middle of the upper inner wall of the upper spray arm is mounted in a plastic guide with rubber seal. Any contamination or damage to the bearings may block the rotation function. If there is no cause externally, the spray arm must be disassembled as specified in the manufacturer's instructions. A porous seal must be replaced, a calcified seal can be reinstalled after cleaning.
