# Bosch error code E:10 / -00 / -10 / -20

### What this one means

The pump for the automatic detergent dosing system is blocked. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- The dosing pump unit
- Detergent that has dried in it

### What to try yourself

- Put the machine into standby and clean the dosing pump unit
- Consider switching the automatic dosing off temporarily so the machine can be used

### Then what

Only the machines with automatic dosing have this. Thick detergents and long gaps between washes are what dry in the unit, and it can be turned off manually while it waits for a repair.

This code is published for washers. The [full list of codes](https://boschmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
