Hotpoint Dishwasher Error codes

Hotpoint is one of the leading dishwasher brands in the UK, preferred by thousands because of their reliable products and competitive prices. A great feature of Hotpoint dishwashers is their built-in diagnostic system, meaning that LED lights on the panel will display a number that corresponds to what has gone wrong in the machine. 

If you already own a Hotpoint appliance, you may be familiar with Hotpoint dishwasher flashing lights or Hotpoint dishwasher error codes. This short guide provides all the information you need to decode the fault code system so that you can make changes or repairs to your machine to get it up and running again. 

These Hotpoint dishwasher fault codes may not cover every single appliance, and not all of the recommended solutions should be attempted by the consumer. If your Hotpoint dishwasher is faulty, be sure to contact Glotech Repairs to organise an appointment with our qualified engineers. Some repairs need to be carried out by a trained professional.
