Describe the appearance
Say whether the finish is patchy, gritty or a uniform haze and whether plates are affected too. Do not assume the appliance is failing to heat simply because glass is dull.
Keep product changes relevant
Include a change of detergent, salt or rinse aid and the selected programme. The model's water treatment instructions matter because settings from another machine may not apply. Assessment should consider the wash result before attributing it to a component.
