Questions people ask
- What does HE mean on a Samsung dishwasher?
- The water is not heating: the temperature did not rise the way the cycle expects. In a limited way, yes, which makes this one of the milder codes here. Some machines finish in cold water. Dishes come out wet and greasy, glasses cloud over and nothing is sanitised, but nothing is unsafe. Book the repair rather than dropping everything. Start here: run the kitchen hot tap before starting a cycle.
- What does HE mean on an LG dishwasher?
- The water did not reach the temperature the cycle needs in the time allowed. In a limited way, yes, and that makes this code unusual. Some machines finish the cycle in cold water and stop there. The dishes come out wet and not properly clean, glassware films over, and nothing is sanitised, but nothing is unsafe either. Treat it as a repair to book rather than an emergency. Start here: run the hot tap at the sink first, then start the machine.
Do not see your machine? We publish a brand only once its codes are confirmed against manufacturer documentation and a second independent source. That is slower than guessing, and it is the whole point of the site.
This is not a coincidence of one code: we compared every code that appears on more than one brand and found that several mean the opposite depending on the badge.
