Error 11 in Ariston dishwasher

When making an application for the departure of the RemBytTekh master, users of Ariston dishwashers often describe the problem as follows: they turned on the equipment, it began to draw water, but after 5 minutes it gave error 11. At the same time, the circulation pump does not start, the light on the power button often flashes, and collected water is drained. As a result, the dishwashing cycle does not start.

Error decoding

Error 11 in the Hotpoint-Ariston dishwasher means a malfunction in the circulation pump. For some reason it doesn’t create enough pressure to circulate the water, so the wash won’t start.

What can you do yourself

Here are the cases in which error 11 can be dealt with without the involvement of a specialist.

• One-time failure of the control unit. Unplug the dishwasher, wait 5-10 minutes and plug it back in. If the error does not appear on the display when you restart the program, then this is not a breakdown, but a banal software failure.

• The filters at the bottom of the chamber are clogged. To restore the operation of the dishwasher, it is enough to remove and clean the filters located at the bottom of the dishwasher. They may contain leftover food and fat. Detailed instructions for cleaning the filters can be found in the instruction manual for your Ariston dishwasher. You need to check them regularly.

• The Hotpoint-Ariston dishwasher is not installed correctly. Check that the drain hose is above the water level in the wash chamber. Otherwise, the water will flow into the sewer by gravity, and the circulation pump will not be able to create enough pressure to wash the dishes.

Possible malfunctions

For 20 years of repairing Ariston dishwashers, the RemBytTech team has collected the main breakdowns, which are signaled by error 11. Let’s take a closer look at each of them.

Circulation pump defective

What exactly happened, the master determines during the diagnosis. But there are three main causes of pump failure:

• the pump motor burned out, without which the operation of the unit is impossible;
• clogging has occurred (the impeller is blocked or difficult to rotate due to clogging of the pump with solid food residues);
• the circulation pump is worn out (the impeller shaft is loose, so it touches the pump housing during rotation, and it cannot pump water normally).

signs

The Hotpoint-Ariston dishwasher goes into error 11 5 minutes after being turned on. The machine draws water, unsuccessfully tries to start the circulation pump, then the water drains, and the dishwasher shows error 11. At the same time:

• if the pump burned out, you will not hear any noise from the pump either before the error or after;
• if there is a blockage, the pump hums, but does not pump water;
• if the pump is worn out, a loud noise is heard from the impeller when it clings to the housing, but the pressure is weak or absent.

How to eliminate

If the motor is burned out or worn out, the circulation pump must be replaced. In case of blockage, you can get by with a little blood: remove, clean and install the pump in place.

Control board failed

The board is the brain center that controls all the nodes of the dishwasher, including the circulation pump. If the radio elements in the circulation pump circuit fail, the contacts and / or tracks are damaged, the pump does not turn on, the Ariston dishwasher does not wash the dishes and gives error 11.

The board usually fails for the following reasons:

• water ingress on the microcircuit;
• sudden power surges;
• high humidity level in the room where the dishwasher is installed.

signs

The Ariston dishwasher draws water, costs about 5 minutes, drains it and writes error 11. The circulation pump does not turn on.

How to eliminate

The wizard checks the circuit of the circulation pump on the control board and, if necessary:

• conducts soldering of burnt or oxidized contacts and tracks;
• replaces failed radioelements with new ones;
• changes the entire control module in case of serious damage to the board or failure of the processor.

Damaged wiring or loose contacts in the circulation pump circuit

In Ariston dishwashers, error code 11 is possible when communication / power is interrupted between the circulation pump and the control board. The contacts of the chips move away due to vibrations during the operation of the equipment. For the same reason, the wiring is sometimes frayed. In private homes, it is also damaged by rodents – ordinary mice or rats.

signs

You start the program, the dishwasher turns on, draws water, but drains it after 5 minutes and error 11 lights up on the display. The circulation pump cannot be heard.

How to eliminate

If the contact in the pump circuit has gone, the master corrects it. If the wiring is damaged, the master twists the wires using heat shrink technology, or completely replaces the cable with wires.
