What to do if my Landa Pressure Washer has a pilot flame, but the main burner will not turn on?

If your Landa Pressure Washer has a pilot flame, but the main burner will not turn on, it could be due to a faulty main valve coil in the gas valve, a faulty ignitor/sensor and/or its wiring, or the ground wire not being attached to the machine chassis. Set test meter to 24 volt scale. With pilot flame on ignitor/sensor, probe terminals MV and MV/PV on the ignition control unit. If you read 24 volts here, but not at the gas valve, there is a loose wiring connection. Repair or replace as needed. If you do read 24 volts at MV and MV/PV and the pilot flame is impinging on the ignitor/sensor rod, the problems may be: a. Faulty ignitor/sensor and/or its wiring.
