The drain Hose Drain Extension Kit, Part No. 7801894, which includes the joiner and clamps, will extend the length of your drain hose when added to the existing drain hose – adding up to 2 metres.
The length of the drain or outlet hose should not exceed (4) metres. This is because if the hose is too long, the pump-out time will be increased ‐ which may lead to unnecessary service calls.
It is strongly recommended that the inlet water hose never be joined, either purchase a longer inlet hose or call a plumber to bring the tap to the dishwasher.
