I need a 10' drain hose for my Bosch dishwasher.
Answer Hello Anthony,
Since the drain hose for Bosch dishwashers are of a metric diameter, only these 00298564 can be used. Since the drain pump is only designed to push the water out the length of the drain hose on the unit, it is not advised to extend it. Bosch does not make an extension for this reason. If the hose is elevated to the countertop height there can be a standpipe installed or a drain line with a proper anti-siphon air gap installed but the drain after the air gap must be downhill to the drain. If an extension is connected there is a possibility of a water leak and/or unsatisfactory wash result.
