What a dishwasher flap valve housing does

A flap valve opens to let water or air move in one direction and closes to stop it flowing back. The housing holds the flap in position and connects it to the surrounding pipework. If the housing cracks or warps, or the flap no longer seats against it, the valve stops doing its job. Depending on where it sits, you might see water leaking under the machine, dirty water flowing back into the tub, slow draining or odours that linger after a cycle. Inspect the housing for splits, a distorted seat or a missing flap, and clear any food or grease build up while you are there.
