Boiler will not start after summer, pump or fan appears stuck

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Pump rotor seized due to sludge, Fan bearings stuck, Sticking gas valve

Safety first: Isolate power and gas before attempting to free any mechanical parts.

Steps (technician):

Free pump: Remove the pump head or access plug and gently turn the rotor with a screwdriver until it moves freely.
Check fan: Remove the combustion cover and rotate the fan impeller by hand to ensure free movement.
Service system: Consider flushing the system and adding inhibitor to reduce future sticking.

If components cannot be freed or seize again, replace the affected pump or fan.
