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.

Hotpoint dishwasher error codes

Flashing NumberFaultPossible causes
A-1Overflow, water in base. Float switch activatedFinding the leak can require some patience and experience. Look for signs where water has been leaking for a while on the circulation motor and other components. Check the fill hose if you have aquastop.
A-2Valve or turbine faulty or disconnected. Machine not sensing the water flow into applianceCheck turbine is turning freely, inlet valve leaking when off.
A-3Time-out on draining, not draining fast enough or not draining at all.Check drain pump, blockages in pipes or behind filters. Module.
A-4Thermistor circuitThermistor or Module faulty.
A-5Pressure switchMesh plate, filter or microfilter. Pressure switch. Circulation pump
A-6Time out on fillingCheck tap is on and water pressure. Inlet valve. Connnections blockage in fill hose. Water flow turbine stuck or faulty
A-7Turbine faultyModule has detected no turbine rotation. Check turbine and wiring.
A-8Time out heatingHeater fault. NTC thermistor detached from casing or faulty.
A-9Software recognition faultModule not programmed or faulty. Wrong keypad.
A-10Heating CircuitHeating element, connections, module pcb, relay or pressure switch.
A-12Communication errorCommunication error between boards. Could be faulty board or wiring. Check all connections first.
A-13Non-operative modulePCB fault.

This list is intended to help you understand the issue(s) your Hotpoint dishwasher may be having.

My Hotpoint dishwasher is not functioning and is showing a code 15.

This is probably do to either the circulation or drain pump being blocked or faulty. There could be debris inside the chamber or they are not functioning correctly.

With reference to the A13 code. What is a PCB? And what is the required diagnosis for this problem.?

Many thanks.

With this kind of fault it is better to get an engineer out as they will carry the risk for diagnosis.

The PCB is short for printed circuit board and is the part with all the electronic components soldered on that carries out the control of the dishwasher. All modern equipment have pcb’s in them like computers etc.

The main problem with faults regarding PCB’s is that you are relying on the faulty part to give you the information (as the PCB will be supplying the fault information). Modern domestic appliances are built to a price and the investment from manufacturers into the serviceability of the products is lacking so the information is not always 100% accurate.

The reason I am saying this is that the PCB’s are expensive and there is a risk that after fitting it will not cure the fault. Also it is possible that there is another fault on the dishwasher causing damage to the PCB, in this case you have to identify the problem as well as purchase an additional PCB as they are not returnable for exactly this reason.

Please read the reply below to Nigel Gaskell’s comment. This kind of fault is difficult to check and expensive to put a PCB in to try it.

If you would like to get one of our engineers out then please Book a repair with Glotech
