Rheem Combi Boiler Error Codes
Rheem Prestige boilers and tankless units display a numeric code on the controller. Note the code before calling.
This is not a DIY repair
Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
