Bosch hot water system

As with any appliance, though, at times faults can occur with your hot water heater that will need to be attended to.

Thankfully, Bosch have thought of everything and have introduced smart technology into their hot water heaters. If you have a hot water temperature controller installed, or a Bosch hot water heat pump, then an error code will display in the event of a problem within the hot water unit.

These Bosch hot water fault codes allow you to quickly and easily know exactly what is causing your hot water heater to not operate as intended, as well as allowing for a fast and affordable repair, or resolve, to the issue.

If a Bosch error code E04 is displayed on my hot water heater what does this mean?

If there is a flashing E04 code on your Bosch Compress 3000 heat pump hot water heater this indicates that the water temperature in the storage tank is greater than 80°C.

Hot water stored in a storage tank needs to be at a minimum setting of 60°C to eliminate the risk of the Legionella bacteria but if it reaches above 80°C in the Bosch heat pump storage cylinder then this is way too high.

Stored water that is too hot could greatly increase the risk of hot water scalding, as well as increase your energy bills from the system working in overdrive.

For your storage tank water temperature to reach this high then there is more than likely a problem with the systems thermostat. In some instances the appliance may shut itself off in the event of an E04 Bosch fault code.
