The error UE in your boiler comes from a blocked drain in the condensate system. The condensate system is the water that helps cool down the furnace. That’s why you get an error UE if there isn’t enough water in the system to prevent it from overheating.
The first thing to do whenever you get this error message is to unblock the drain. You can use a chemical like Simple Green or acetone to dissolve any grease and other substances clogging it up, flush it out with lots of water, or use a plunger and bend some wire hangers into hooks to pull out whatever’s blocking it. Be careful not to scratch anything!
If that doesn’t work, you’ll need to disconnect any pipes running into or out of the condensate pump (the pipe connecting it to your water supply) and flush them out by pouring lots of hot.
A faulty thermostat often causes this error. This can be fixed by resetting the thermostat and then turning it off for 20 minutes.
