HH/hh Error Code Worcester-Bosch Boiler

Описание: What does a Worcester Bosch boiler HH/hh code mean?

To ensure your boiler continues to operate optimally and effectively, regular maintenance is key. In fact, it's recommended to have your Worcester Bosch CDi, Ci, Si boiler, Greenstar, or Junior Boiler serviced annually. If you haven’t booked your annual boiler service, click on the link below.

But what does it mean when your Worcester Bosch boiler displays an HH/hh symbol? Don't worry; it's not a fault code. This symbol indicates that your boiler is in commissioning mode.

Commissioning mode is a setup program that ensures everything is functioning correctly with your boiler. So, when you see this symbol, simply wait for the boiler to complete its cycle. There's no need to panic.

However, in some cases, prolonged disruptions or fluctuations in the power supply can cause your boiler to re-enter the commissioning mode. It's important to note that Worcester Bosch boilers must go through this cycle before any other attempts at use or testing can be made.

Occasionally, your Worcester Bosch boiler may enter a "Locked Out" mode. When this happens, the gas supply will cease until the boiler is reset and returned to normal operation. Although it may seem like an issue with an unplugged sensor, this particular problem is not mentioned in the manufacturer's instructions.

To resolve this situation, your Worcester Bosch boiler must remain in the "Locked Out" mode for approximately 20 minutes to half an hour before returning to regular operation. During this period, your boiler may still provide hot water, but standard heating modes will not be accessible. Please note that the reset button will not bypass this mode quickly; you'll need to wait a while longer for the boiler to return to its standard service.
