Re: Tecnik TKL925.
I discovered something else to watch out for on these machines the hard way yesterday. Don’t inadvertently insert the wash heater element upside down, and it will go right in upside down, as it’s very difficult to get back out again. You only realise it’s upside down when the terminals end up almost touching the outer tub!
I don’t know if this problem applies to both sizes of heater; I discovered it on a model with a shallow heater backplate. Some models have a deeper one.
