Hi Guys,
Jus had a quick question, had a customer call me saying there is no hot water or CH and boiler is flashing L8.
Had a look at the MI troubleshooting page which said could be fan error, pcb error or wiring harness. Disconnected the fan connector and was not getting the nominal 330 V DC across red and blue at the connector with the rest button pressed however got continuity on wiring harness. MI suggested to replaced wiring harness.
I reconnected the fan connector and reset the boiler after which the boiler started to work however the burner comes on for few minutes cuts out and then comes back on again after few minutes and keeps cycling like this.
Has anyone had this issues before, would this be due to a faulty pcb, fan, wiring harness.
Thanks
