Biasi Boiler Problems and Common Fault Codes

After you have your new Biasi boiler installed, you have to keep yourself prepared for anything that might happen.

While the boilers are well built, it’s not to say they will not run into problems. When they do, you should have enough information to know what to do. Some of the fixes are simple and others require that you call an expert to assist.

Boiler won’t ignite

It’s not easy to find out why a boiler won’t fire. There are several issues that could cause this problem. It’s possible the fain isn’t operation, the burner has a problem or the gas supply is intermittent.

Suggested fix

Depending on the problem, the fix can be simple or complicated. No matter what the problem could be, you need to call in an expert.

The first hint is the fault code displayed on the panel. It can help to determine what the problem could be with the boiler. The error codes can range from ER01 to ER05. The fix will depend on what the problem is.

No hot water

In most cases, a lack of hot water is caused by a faulty diverter valve. If the diverter valve is the problem, it can result in other issues like:

  • Lack of hot water even when the heating works fine
  • No heating even when hot water works fine.
  • Radiators heating up slightly when you’re running taps or showers.

Diverter valves can get still or get stuck. They can get stuck in between, on the heating side, or the hot waterside.

Suggested fix

If the valve is only stuck and is in good condition, an engineer can help free it. If it’s old you might want to consider a replacement. This will prevent the same situation from occurring again.

Boiler flashes with ER04

An ER 04 fault code relates to water. The problem is either lack of water or limited or no circulation of water in the system.

Suggested fix

Start by checking the boiler’s pressure. If the pressure is low, you need to top it up correctly using the external filling loop.

If the boiler pressure is fine, then it could be a circulation fault. In most Biasi boilers the problem is usually because of a fault with the pump.

To troubleshoot this and fix the pump, you will need to have an engineer come in and check the pump and he can advise on the best way forward.
