Error 15 in the Hotpoint-Ariston dishwasher

Did the Hotpoint-Ariston dishwasher start giving error 15 at the beginning of the program before pouring water into the tank or after rinsing the dishes and draining the water? The dishes in both cases remain dirty. Let’s figure out why this happens, and what to do in this situation.

What does error code 15 mean

Error 15 in Hotpoint-Ariston dishwashers reports problems with water heating. Modern models check the health of the heating before starting the program, so they give an error immediately when turned on. Old Ariston dishwashers show code 15 when the program reaches heating. This usually happens after pre-rinsing the dishes with water.

What can you do yourself

With error 15, the control unit may fail. To eliminate this temporary defect, unplug the power cord, wait about 5-10 minutes and plug the dishwasher back in. If the error disappears and does not appear again on subsequent launches, then there was a one-time failure, and repair is not needed.

Possible malfunctions

The masters of the RemBytTekh service center have been working with Hotpoint-Ariston dishwashers for more than 20 years. Among the entire list of codes that signal possible breakdowns, error 15 is quite common. It indicates the following faults.

TEN burned out

Usually the heater spiral burns, so it does not work. Significantly increases the likelihood of burnout of the heating element coil due to scale on its surface due to too hard water.

Note! To prevent the heating element from failing quickly, set the correct water hardness when initially setting up the dishwasher.

signs

The Hotpoint-Ariston dishwasher gives error 15 when it is turned on or after pre-rinsing, when the heating should turn on. The water does not heat up.

How to eliminate

The heating element needs to be replaced. In Ariston dishwasher models with a flow heater built into the circulation pump, the entire assembly changes.

Control board failed

The radio elements in the heating element circuit on the control board fail, their contacts and tracks oxidize or burn. The reasons for such a breakdown can be:

• power surges;
• water hitting the surface of the control board;
• too high humidity level in the room.

signs

The Ariston dishwasher gives error 15 when turned on and does not start the selected program. When restarted, the problem recurs.

How to eliminate

The wizard identifies faulty areas on the control board. Oxidized or burnt contacts of elements and tracks are soldered. Faulty radioelements are replaced with new ones. If during the diagnostic process it turns out that the processor is not working or more than 30% of the board is damaged, he will replace the entire control module.

Damaged wiring or loose heater contact

The vibrations of the dishwasher during washing eventually lead to problems such as chafing of the wiring in the heating element circuit, or loss of contact. In addition, mice often gnaw through the wiring in private homes.

signs

The technique writes error 15 immediately when it is turned on or after rinsing the dishes. The heating does not work, the dishes remain dirty.

How to eliminate

If the contact of the heating element has gone, the master corrects it. If the wiring is damaged, he twists the wires with heat shrink or changes the cable assembly with the wires.
