# Bosch washer will not start

### The fastest diagnosis is the code

There are separate published codes for "the door is not locked" and "water is not arriving", and they are the two commonest reasons a cycle never begins. Photograph whichever one is showing — it saves the first half of the diagnosis.

### The two published reasons

These machines have separate codes for a door that is not locked and for water that is not arriving, and between them those are most of these calls. That is unusually specific, and it means a photograph of the display genuinely does half the diagnosis before anybody drives out.

### Inlet screens

There is a fine mesh filter in the inlet fitting where the hose meets the machine, and in a hard-water city it blocks. It can be cleaned with a small brush in a few minutes with the tap off, and it is the sort of thing nobody thinks to look at.

The door is not shut properly

It has to click. A full load pressing against it, or something caught between the door and the seal, will stop it — and there is a code that says exactly this.

The door lock

Closes but does not report locked. The machine will not fill without that confirmation, which is sensible.

Water not arriving

Tap closed, inlet filter blocked, hose kinked, or genuinely low pressure. Blocked inlet filters are common in this city's water.

The breaker, or a socket in a closet that shares a circuit with something else. A machine with no lights at all is power until proven otherwise.

Child lock or delay start

Both are easy to set by accident and both look exactly like a dead machine.

Close the door hard enough to click

And check nothing is caught in the seal. A sleeve in the door is enough.

Check the tap and the inlet screen

The tap fully open, the hose unkinked. The filter screen in the inlet fitting can be cleaned with a small brush.

Cut power for five minutes

Genuinely off at the breaker. It clears a surprising number, especially after a power cut.

Look for a lock or a timer

Child lock, or a delay start left on from last week.

Door, power or supply

What it usually means

No response at all

Lights on but the cycle never begins

Starts, then stops without filling
