Error 13 on a Hotpoint Ariston dishwasher

A breakdown of all the error codes that your Hotpoint Ariston dishwasher may display is available in the machine's manual. Error 13 (or A13 for some models) indicates a problem with the detergent dispenser. This means the dishwasher is unable to open the dispenser. We'll explore the main causes of this problem and explain how to fix it.

Does the dishwasher dispenser work?

What should I do if I find my dishwasher not working and displaying this error code? Error 13 is displayed on the display 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 this situation is simple: simply remove the obstruction by rearranging the dishes in the baskets. The user will need to move any items that could potentially obstruct the dispenser opening. These are typically large cutlery items, such as pots and pans with long handles.

If the dish does not prevent the dispenser lid from opening, the dispenser mechanism itself is probably damaged.

First, inspect the detergent compartment. Sometimes the problem is a buildup of residue on the walls of the dispenser. Try thoroughly rinsing the dispenser; this may help clear the error code.

If the mechanism is damaged, the dispenser will need to be replaced. Parts are purchased for the specific Hotpoint Ariston dishwasher model. Replacement is easy to do yourself at home: unplug the machine, remove the old dispenser, and attach the new one.

Dispenser solenoid relay

Sometimes error 13 is caused by a burnt-out solenoid relay. Without it, the control module cannot command the dispenser to open. This error code appears on the display during the first few minutes after startup, when the Hotpoint Ariston dishwasher is filling with water. Due to the noise of pouring liquid, the user cannot tell whether the click signaling the dispenser lid opening was heard or not.

Before accessing the control board, experts recommend resetting your Hotpoint Ariston dishwasher to rule out a system failure. To do this:

• turn off the dishwasher using the button;
• unplug the machine's power cord from the socket;
• wait 20-30 minutes;
• plug in the dishwasher, wait 5 minutes;
• start the machine by pressing the "On" button;
• Select a short wash program and start the cycle.

Sometimes these steps help clear error 13. You can try the reboot three times. If the error code still appears on the dashboard, you'll need to check the control module.

Next you will need to:

• de-energize the dishwasher;
• 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 part 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 everything is visually OK with the electronic unit, you will have to check it with a multimeter.

The entire module is not tested, but rather the dispenser solenoid relay. The trace leading to the semiconductor is also tested. Repair will involve removing the damaged component, re-soldering the circuit, and installing a working relay. Working with dishwasher electronics requires specific knowledge, so it's best to seek professional assistance.

If your Hotpoint Ariston dishwasher is still under warranty, do not attempt to repair it yourself. Bring it to a service center for a free diagnostic.
