Remove the drip tray, lower panel, silicone dispense hose and the inner cover.
Connect a hose from the overflow pipe to a bucket and open the service valve to
drain the water from the tank.
Flush the tank with clean water, shut the valve and replace the covers.
Replace the drip tray and tank lid, ensuring the gasket is sealing the top of the tank
correctly. Re-fit the outer lid and turn on the boiler.
