I bought *********************************************** dish drawer dishwasher in Q4 2023. My *********************************************** dishwasher is not cleaning dishes 3 months after purchase. It cost more than double of a Bosch dishwasher and not working in 3 months. They sent same tech twice and he kept saying it is my water heater problem. His diagnosis is to run hot water for 10 minute until really hot in my kitchen and then run dishwasher and keep increasing water heater temperature. Even though it does not make sense, I did increase my water heater to a level before it is extreme hot and ran hot water until really hot in the kitchen tap. Still not cleaning. He is saying dishwasher does not have heat pump that heats the water. It does not make sense. I would like my dishwasher to be fixed or replaced. It is defective for sure and tech kept blaming me. I have extreme hot water during shower and other taps and still he kept blaming my water heater which I have no complain at all. You can see in attached images that my water heater is last level before it is dangerously hot. I have also done online research and in the review answered by *********************************************** that the dishwasher should heat its own water. I have been using dishwasher for 24 years and never had this problem. I had regular brand such as kenmore or other economical brand and neve had any issue. This is more than double price of Bosch and 4 times more than economical dishwasher and performance is so bad! I would like Fisher and Paykel to repair, proper test or replace if cannot fix
