F01 (blocking error)
Defect in power supply
circuit Live and neutral connected wrong way
around. Be sure to connect the live and neutral
correctly (see section 7.8); the water heater
is phase-sensitive
Condensation on the flame probe Disconnect the lead at the flame probe
Ignite the water heater three times, with
an interrupted ionisation circuit
Reconnect the ionisation lead to the
flame probe
Ignite the water heater again
The repeated ignition attempts will have
caused the condensation to evaporate •
