E02 in brief
Bosch's list gives E02 two possible readings: the icemaker itself is faulty, or the controls that run the ice and water system have a communication issue. Either way, in most cases the refrigerator and freezer keep cooling while ice production stops. Start with the simple checks, such as the icemaker switch and the water supply, then restart the refrigerator; if E02 returns, the icemaker or its control link needs testing.
Error codes
Reference| Code | Meaning |
|---|---|
| E02 | The icemaker is faulty or the ice water system controls have a communication issue. |
What you notice with E02
- No new ice in the bin — The icemaker has stopped producing.
- Ice cubes that are small, hollow or stuck together — Water supply or icemaker problems change the cubes before production stops.
- The dispenser does not respond — If the ice and water controls are not communicating, dispensing can stop.
- Fresh food and freezer temperatures stay normal — Cooling is handled separately, so the food stays cold.
Likely causes, ranked
- The icemaker switched off or blocked — First: an icemaker turned off, a bin that is not seated properly or a jammed arm stops production.
- Water supply problems — Second: a closed valve, a kinked line or a clogged filter starves the icemaker.
- An icemaker fault — Third: the motor or the icemaker's own electronics can fail.
- A communication fault between the controls — Fourth: the wiring or connectors between the icemaker and the main control can fail, or a board can stop responding.
The order to check
- Make sure the icemaker is switched on — Check the switch or the setting on the icemaker or in the menu.
- Check the bin and the icemaker arm — Remove the bin, break up clumps, and look for ice jammed in the mould.
- Test the water dispenser — If water does not flow, the supply or the filter is the likely problem.
- Restart the refrigerator — Unplug it for a few minutes or switch off its breaker, then restore power.

Safety around the refrigerator
Safety
Unplug the refrigerator or switch off its breaker before reaching into the icemaker area, and keep fingers away from the ejector arm, which can move without warning when power returns. Refrigerator control boards can hold a charge after the power is cut, so do not remove covers. A full-size refrigerator is heavy, so get help if it must be pulled out to check the water line.
When E02 needs a professional
Arrange a visit if E02 returns after the icemaker, bin and water supply have been checked, or if the dispenser stays unresponsive. A professional tests the icemaker and the communication between the controls, which requires removing covers inside the freezer or behind the refrigerator.
