Common dishwasher problems – unwanted noise

This is not uncommon with dishwashers. Most dishwashers have an anti-flood device installed. This device can be simple, such as a float and switch or a complicated unit activated by pressure or back pressure. Either way, the device will switch on the drain pump when activated, this clears the dishwasher sump of water, it also disables the filling circuits or valves on the dishwasher. Therefore it will not fill with water whilst the anti flood mechanism is activated, both measures ensure that the incoming water supply is stopped whilst reducing the water that escapes to your floor. This is quite a tricky job. To resolve this problem contact us here
