Error 10 on Rinnai. Burners were plugged up. I blew them out with compressed nitrogen. We ran multiple fixtures to ensure hot water. 140F set at the tank which is very hot. I confirmed with client that it has always been set at that temperature.

I found that the blower motor has failed. I replaced the blower motor, the capacitor and cleaned the squirrel cage and blower housing assembly. I tested operations and the unit is cooling. I would highly recommend a maintenance to be done. The outside coil was very dirty. Regarding the sweating water pipes I can reach out to the team for ideas.

Cleaned up the pump internals and it is working. A piece on the pump is slightly broken but I was able to seal it. I cycled over a quart of water through the pump and no leaks. I reccomend replacing the pump with a better option.

I needed to have shut off valves under my kitchen sink and a new hose attachment on my sprayer since the cheap plastic tubing was cracked. Mark was punctual, professional and extremely knowledgeable regarding the job. I am always impressed with GSM and how they run their family business. Mark completed the job quickly and efficiently. I can trust GSM and will continue to seek their help in the help in the future. GSM has installed a mini split, oil boiler, hot water heater in my home and I would highly recommend them to family and friends.
