Description: Before ordering the spares, check that your...

Pull the reservoir off upwards and empty.
Remove the drip tray and empty.
Turn the coffee maker upside down over the sink to get as much water out as possible.

Flip the coffee maker on its back
Using a right angled rachet screwdriver, with a Philips No.2 head, unscrew the stainless steel filter from the underside of the top section.
It will probably be filthy and need cleaning with hot water and a scrubbing brush. Use a pin to remove any blockages from the holes of the filter. You can also use a TeePee dental brush to remove debris from around the screw hole where the water comes out.

Flip the coffee maker over. The bottom cover is held on by 2 torx screws just to the rear of the front supports and two clips to the rear. Pull the bottom upwards from the front to release. The bottom cover then just clicks out to reveal the bottom of the pump.

Remove the clear tubes from the reservoir valve that you have just exposed. They just pull off. Empty any water from the tubes.
Take a look at the filter that is in line with the pump inlet. This is often filled with bits of coffee. It is very hard to clean, but holding it under a tap with running water can be used to remove them.

The top cover is held on by 4 torx screws - two on the rear of the top by the reservoir down dark holes, and two on the underside of the front, near the boiler filter. The filter cover should just click off. Don't bother to remove any of the wiring to the controls

Pull the top knob off vertically - it is held on by friction to splines. You may need to give it some assistance with a screwdriver or iFixit levers.

Pull the clear tube out of the top of the coffee maker.
Locate the white plastic 3-way valve at the rear top of the machine. This is the Over Pressure Valve, and controls the pressure of the water flowing into the boiler through a simple spring mechanism. The excess water is returned to the reservoir via the clear plastic tube.
Pull the clip out of the valve that attaches a small tube to the boiler. You'll see that the clip traps a brass collar around the tube into the valve. Pull the tube clear.
Rotate the valve anti-clockwise to unscrew it from the pump. It can be a bit difficult to move.

Unscrew the 4 screws holding the boiler down to the plastic sub-chassis.
Gently remove the boiler upwards, without disconnecting the wires.
The screws are retained by plastic widgets which will probably fall out when you remove the boiler. These simply slot back into the holes around the boiler hole in the chassis.

The plastic sub-chassis should now lever up with gentle persuasion and a bit of native cunning. You may need to use plastic picks etc to lever out the catches.

The pump should now be visible. Pull the rubber mounting plate upwards to release the pump.
Remove the two lucar connectors with blue wires from the pump.
