# Bosch error code Four lights flashing with a beep

### What this one means

The machine has stopped on a condition it cannot describe any more precisely. 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.

### The other ways your machine may say it

The same condition is published under more than one label, because it has been carried across generations of this appliance:

- **Four lights flashing along with beeping** — how a model with no digital display says it. On that machine, the lights are the code

### 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:

- Anything the machine treats as serious enough to stop for

### What to try yourself

- Press ON/OFF
- Cut power at the breaker or pull the plug and wait a full two minutes
- Switch it back on and try one cycle

### Then what

On a machine with no display this is the equivalent of a code the display would have shown. The two-minute wait matters — thirty seconds is not always enough for the electronics to reset properly.

This code is published for dishwashers. 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.
