Frequently Asked Questions - GH187 BUFFALO

How do I set up the water boiler for first use?

Remove the yellow steam cap from the steam pipe (see steam label on front). Remove any warning labels covering the controller. Switch on the mains water supply and electricity supply. Leave the appliance to fill and heat water for 15 minutes. Draw water from the tap until the flow stops. Repeat the filling and drawing process. Leave to fill and heat again. The appliance is now ready for use.

How do I replace the water filter (GC719 model)?

When the red LED on the controller flashes, replace the filter. Remove the drip tray. Twist the cartridge 90° (1/4 turn) counterclockwise to unlock. Insert a new filter cartridge into the filter head and turn clockwise to lock. To reset the filter warning, place your fingers on the controller screen as indicated in the manual.

What does a steady red light on the controller mean?

A steady red light indicates that descaling or maintenance is required. Follow the descaling procedure in the manual. If the light stays on after descaling, contact the manufacturer.

A flashing red light indicates that the water filter needs to be replaced. Follow the filter replacement procedure for filtered models (GC719) and reset the warning.

How do I descale the water boiler?

Descaling must be performed by trained personnel. Isolate the boiler from the electrical supply and allow water to cool to approx. 60°C. Remove the top cover and tank lid, add descaling agent suitable for stainless steel, replace lid and cover, turn on electricity for 45 minutes. Then isolate, cool, drain, and flush the tank. Ensure not to damage the level sensor probes. Failure to descale regularly invalidates the warranty.

The boiler is supplied with a 13 amp plug. If replacing the plug, connect the terminals as follows:

GREEN and YELLOW wire EARTH - E

BLUE wire NEUTRAL - N

BROWN wire LIVE - L

For safety regulations the plug or means of disconnection must always be accessible.

Water Connection:

Connect the supplied inlet hose to the inlet connection point on the base of the appliance and the other end to the mains cold water supply.

Overflow & Drainage

Due to the electronic function of the appliance it is highly unlikely that an overflow would occur. The appliance is designed so that any overflow occurrence and condensation is directly vented into the drip tray.
