Snap Error
Snap disc triggered or low water
cutoff has triggered.
Wait for boiler too cool, thus allowing the snap disc
to reset. If the boiler does not reset, replace the
snap disc.
Check the door seals for leaks.
Check the pump for proper flow.
Adjust the draw on the stove or the wood load.
Check the water pressure in the boiler. If low, add
water.
Fan Error
Fan torque applied but not getting
tach signal
Disconnect power and check the fan connections.
If the connections are not the cause, disconnect
power, allow the boiler to cool, and remove the
fan to inspect for damage or creosote/ash buildup.
Clean if needed.
If damage to the fan is found, or if the fan still fails
to work, replace the fan.
If none of these suggestions appear to solve your problem, contact your dealer.
