That is unusual and it is a gift: the machine tells you before the damage is done. Descaling is a maintenance figure. Replacing a heat pump that spent a year encrusted is not. ### What decides the figure - Descaling, where the machine has said so and nothing else has failed: the low end - A drying fan or a mineral chamber heater on the upper series: mid - The heat pump assembly: the top of the range, because several functions are combined in one part and it is priced accordingly What this involves Heat pump and heating circuit The mineral drying system on upper series Glassware wet, not just plastics Which of the two problems it is Plastics wet and glass dry is the design. Everything wet, or dishes still dirty, is heat — and those are different repairs at different figures. Scale before parts In this city, a heat pump struggling to heat is very often a heat pump full of scale. Descaling is cheaper than the assembly by an order of magnitude and it is checked first. The circuit, measured The heat pump, its internal heater and the sensors around it, tested rather than assumed. The published codes cover the circuit; the meter says which end of it. A hot cycle, verified The machine is run and the water temperature confirmed before we sign it off, not inferred from the fact that the code cleared.
