Hotpoint Aquarius FDM Dishwasher flashing lights and there fault codes
Dishwasher not heating time out fault. “Salt and rinse aid lights are flashing, so are the start/pause and the Drying lights.”
Why not fix it yourself following these simple steps in the video and avoid the expensive call out charges of an engineer. A simple service of your dishwasher or replacing parts often solves the problem.
Fault or error codes used in Aquarius range dishwashers produced Hotpoint however, these error codes may apply to a few other dishwasher brands as well. Like Indesit and some Creda.
These fault codes are written for engineers not for the general public we will always help where we can in helping you identify the fault but these codes below will help you.
People need a certain level of competence in using these codes to identify the fault with the dishwasher and you will still need to investigate each failure on its own please enter any questions you have below this article.
