[ All models ](https://esbosch.djwp.xyz/models/) In more detail ## About Bosch dishwasher will not start ### The fastest diagnosis is the code A dishwasher that will not start is very often a dishwasher that does not believe its door is shut. There is a switch the latch operates, and if it does not close the machine will not begin — which is deliberate, given that the door is what keeps the water inside. ### Door, then power, then the board Those three, in that order, explain nearly all of these. The door has to latch and a switch has to confirm it before the machine will do anything, which is sensible in an appliance that fills with water. Power includes the outlet under the sink that shares a switch with the disposal — an outlet a great many people do not know is switched at all. ### The voltage code These machines publish a code for a supply that is too low, which is a genuinely useful thing to be told. It means the problem is upstream of the dishwasher, and no part inside it will improve matters. In older buildings and on long runs it is a real finding rather than a curiosity. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about bosch dishwasher will not start That is a different problem — water supply rather than start-up. Check the valve under the sink is open and the inlet hose is not kinked, and look for a supply code. Common here. Five minutes genuinely off at the breaker fixes a fair number. Those it does not fix often have real surge damage, and that timing is worth telling us. Check the child lock first — it is usually a button held for a few seconds and it is easy to trigger while wiping the panel down.
