Error 13 on a Hotpoint Ariston dishwasher

A decoding of all fault codes that a Hotpoint Ariston dishwasher can produce can be found in the instructions for the equipment. Error 13 (for some models A13) indicates a breakdown in the detergent dispenser. That is, the PMM cannot open the dispenser. Let's look at the main reasons for this problem and tell you how to fix the problem.

Is the PMM dispenser working?

What should you do if you find a non-working dishwasher that displays this fault code? Error 13 is displayed when the dishwasher Hotpoint Ariston cannot open the detergent compartment. Usually the reason is that the lid is blocked - this happens when dishes are loaded into the hopper incorrectly.

Resetting the error in such a situation is simple - just remove the obstacle by arranging the dishes in the baskets differently. The user will need to move objects that, theoretically, could interfere with the opening of the dispenser. Usually these are large cutlery: pots and pans with long handles.

If the dishes do not interfere with the opening of the dispenser lid, the dispenser mechanism itself is probably damaged.

First, inspect the detergent compartment. Sometimes the problem is plaque that accumulates on the walls of the dispenser. Try rinsing the dispenser thoroughly, this may help reset the error code.

If the mechanism is damaged, the dispenser will have to be replaced. Components are purchased for a specific model of Hotpoint Ariston dishwasher. The replacement is easy to do yourself, at home - turn off the power to the machine, remove the old dispenser and secure the new device in place.

Dispenser solenoid relay

Sometimes error 13 is caused by a burnt out solenoid relay.Without it, the control module cannot give a command to open the dispenser. This fault code is displayed on the display in the first minutes after startup, when the Hotpoint Ariston dishwasher fills with water. Due to the noise of the pouring liquid, the user cannot make out whether there was a click indicating the opening of the dispenser lid or not.

Before getting to the control board, experts recommend rebooting the Hotpoint Ariston dishwasher to avoid a system failure. For this:

• turn off the PMM from the button;
• unplug the power cord of the machine from the socket;
• wait 20-30 minutes;
• Plug in the dishwasher and wait 5 minutes;
• start the machine by pressing the “On” button;
• select the short wash program and start the cycle.

Sometimes such actions help to reset error 13. You can repeat the reboot 3 times. If the fault code still appears on the display, you will have to check the control module.

Next you will need:

• de-energize the PMM;
• disconnect the machine from communications;
• open the dishwasher door;
• Unscrew the screws located at the ends of the door and at the back;
• remove the top of the door.

After this, access to the control module will open. There is no need to remove the board - just inspect it for defects: swelling, rust, carbon deposits, oxidized contacts. If visually everything is in order with the electronic unit, you will have to check it with a multimeter.

Not the entire module is checked, namely the dispenser solenoid relay. The track going to the semiconductor is also tested. The repair will consist of dismantling the damaged element, soldering the circuit and installing a working relay. Working with PMM electronics requires certain knowledge, so it is better to seek help from a specialist.

If your Hotpoint Ariston dishwasher is still under warranty, do not attempt to repair it yourself. Submit the device to a service center for free diagnostics.
