Intake/drain light flashes and the dishwasher won't run

Hi,

this is a general fault light which could mean anything without a Miele Technician coming out and connecting a laptop to the unit. However most common faults with dishwashers is a drain fault. Check for any kinked hoses and check the drain spigot under the sink where the drain hose connects into the u bend. Usually this is where food gets trapped due to the spigot not being drilled out large enough. This then causes a blockage. Also check the non return valve under the filter and make sure the drain pump can turn freely.
Hope this helps.
