The Main P.C.B. (FF850): Operating Voltage: 190V – 265V AC @ 50Hz Frequency Range: 47-65 Hz Fuse Rating: 315mA 250V AC Operating temp: 0–70^C This P.C.B. (FF850) controls all the main functions of the machine, monitoring the water level, pressure, water supply etc. If a fault is detected the user is warned via the service or ready L.E.D. Some faults render the machine inoperative whilst others will only give warning flashes 10.0 THE SENSING PROBES: Sensing probes are used to detect the presence of water within the boiler, using a small electrical... -

1a. - Mains Water Pressure: MAINS WATER PRESSURE RANGE: Between 2.0 and 7.0 bar (28 and 96psi) Incoming mains water pressure can vary wildly from site to site and can also fluctuate dependent on the time of day (water pressure often increases at night). In extreme cases, this can take the mains water pressure outside that at which the boiler can operate. - Page 10 To replace the tap spring (Part No.TP1007/N): Switch machine off. Open steam tap to evacuate pressure from boiler. Push the pin out of the tap handle.(the pin has a bend in the middle) Unscrew the tap bonnet and remove the tap assembly from the tap body. ...

Page 11: Scaling
Aerator A water spray assembly known as an “aerator” is attached to the end of the water arm. Its purpose is to allow the user to dispense boiling water without excessive “splash-back”, which can result from the force of pressurised boiling water entering the vessel – particularly a problem if small containers/vessels are being used. -

MACHINE CAUSE SYMPTOM Dead P.C.B. faulty (315mA fuse or transformer) No mains input (installation problem or outside interference) ON/OFF switch faulty Unsound terminal connection Blown fuses in plug (3kw) Bad connection in plug (mains lead fault) Over-ride pressure-switch has switched power off to the... - Page 13 16.0 - SERVICE WARNING CODES: If the amber “Ready” light is flickering – either: mains-water pressure on the premises is low, the water supply has been turned off or there is a scale build up. The light will stop when the water has returned to normal.
