Arrived on site to diagnose no heat on boiler with an F1 error code. Upon inspection, we found that the boiler was only around 10psi. The minimum this boiler calls for is 12psi. Repressurized boiler to around 15psi. Boiler then fired up without any problems. Cycled boiler a couple times and it lit and stayed on each time. No error code present. Boiler seems to be operating properly at this time. If problem ends up coming back we will need to figure out why the boiler system is losing pressure. Customer would also like an estimate for the cost of a combi boiler. They are interested in either a Viessmann or a Rinnai unit. Thank you for your business!
