Help! 😥 I have just installed a new dishwasher (althought it has sat in garage in wrapping for 3 years) and for the first two washes has been fine. Now when I set and close door the prewash cycle lights up and the machine bleeps. The flashing is a single flash.
I have read a few other forums and it seems it mat be the NTC? Would this happen on such a new machine?
