645038 Genuine Micro Filter for Bosch, Siemens, Neff Dishwashers, BSH 00645038 Fine Mesh Dishwasher Filter

Part 645038, also written 00645038, is a genuine BSH micro filter for Bosch, Siemens and Neff dishwashers. It's the fine mesh filter in the sump that stops small food particles circulating back onto the dishes. A cracked or deformed micro filter lets grit through to the pump and spray arms. No model list is on file for this part, so check the number moulded into your old filter or send us the E-Nr.

Gritty dishes and smells point to the micro filter

Water drains through the filter system on its way back to the circulation pump. The coarse part catches bigger scraps, and the micro filter traps fine particles like coffee grounds, seeds and grit. If the mesh tears or the filter no longer locks in properly, that debris gets pumped back over the dishes, leaving a gritty film, and can block spray arm nozzles or damage the pump. Bad smells, standing water in the sump and poor draining can also come from a clogged or worn filter. Rinsing it regularly keeps it working.

Fitting the micro filter

Turn the dishwasher off before reaching into the tub. Lift out the lower basket, then twist and lift the filter assembly from the base of the tub. Fit the new micro filter in the same position as the old one, then refit the assembly and turn it until it locks. A filter that isn't locked in can let debris into the pump.

Questions about this part

How often should the dishwasher filter be cleaned?

Check and rinse it under the tap regularly, and more often if you don't scrape plates. Avoid wire brushes, which can damage the fine mesh. If the mesh is torn or the filter is distorted, cleaning won't fix it and it should be replaced.
