Today I arrived on site to address the no heat or hot water issue. Boiler Repair: Identified ignition faults on the boiler. Replaced the igniter assembly (provided by the customer). The boiler is now igniting after replacing the igniter assembly. System Status: Heating and DHW system is now operational. Upon arriving at the property, the client explained to me that the boiler is displaying a (error code). I proceeded to verify the unit. I found the unit displaying and error code (Ea) indicating ignition failures of the unit. I showed him and explained to the client the situation and about the failure that the system presents. Uncovering the unit, I found a bigger problem related to the unit's heater exchange. The heater exchange is leaking and is overheating the unit causing damage to the electrical components of the boiler. I showed the client and suggested she consider upgrading this system. I informed the client that I would pass all the necessary information to the office
