@plumbingdoctors: Baxi boiler showing an E20 fault code ⚠️ A quick Google search shows E20 is a Central Heating NTC (thermistor) sensor fault 🌡️ Diagnosed the issue and replaced the thermostat/thermistor from stock on the van 🚐🛠️. I did drain the boiler down before remembering it was a dry pocket 🤦‍♂️💧, but while I was there I recharged the expansion vessel anyway 👍 A bit of heat paste on the new sensor 🌡️👌, filled it back up, tested everything, and the boiler was back up and running ✅🔥 #BaxiBoiler #BoilerRepair #GasEngineer #FaultFinding #HeatingEngineer
