🔧 no hot water Worcester Bosch combi 🔧
Customer called to say they had cold water coming from the hot tap, they said the boiler does fire up when a tap opens but remains cold…
They said their pressure was okay and no fault codes on the boiler…
On arrival I saw a Worcester Bosch 30si sat on the wall and when I opened a hot tap the boiler did fire but water was stone cold…
The fact the boiler fires proves the sensor/turbine is okay so the next in the sequence would be to check the diverter valve position
