Questions and answers
Main multipoint ff Water heater is dripping on the left hand side. However when turned on this stops.
A Main MULTIPOINT FF water heater dripping on the left-hand side when it is off could be caused by a leak from internal components such as the heat exchanger, pipe connections, or the water sensor (turbine). Possible causes include:
1. A leaking heat exchanger due to corrosion or damage.
2. Loose or damaged inlet or outlet pipe connections.
3. A faulty or leaking water sensor or associated pipework.
4. Residual water remaining in the system after shutdown draining through a compromised seal or joint.
Inspection of these components and connections is needed to identify the exact source of the leak.
