De-scaling - Including cleaning the probes :
• Disconnect the machine from the power supply.
• Remove the lid
• Remove tank lid.
• Pull gauze retainer off overflow pipe (Important - remember to replace during reassembly).
• Remove baffle plates.
• Remove as much loose scale as possible by hand. Any hard scale coating the level sensing probes and holders, should be cleaned off using a non-metallic scouring pad.
• Use a good de-scaler such as “Renegite” (Part No. ACC303) to remove hard scale deposits. Mix 2-3 packets in hot water and pour into tank. Leave for approximately 20 minutes.
• Flush tank out with water, ensuring that all traces of de-scaler are removed before reassembly.
