Error 15 in the Ariston dishwasher

Error 15 PMM AristonProblem error 15 in the Ariston dishwasher is not so rare. Most often, it pops up in dishwashers of the LTF and LFD series, and it is not very easy to find a true decryption of this error. In this publication, we will not only decode error 15, we will also offer options for finding and eliminating the problems that cause it.

Probable reasons

On some forums, visitors suggest that error 15 is due to the fact that the machine cannot remove the waste water, or removes it, but does not stop pumping. In other words, they believe that this error indicates a pump or a filling valve. It's not like that at all. It is possible that the error is interspersed with some other, so it seems that the drain / flood system is faulty, but in most cases, error 15 indicates a breakdown of the heating element.

This error appears in cases where the control module cannot determine the heater. Why can't a module determine it?

  1. Burned out heating element.
  2. The wiring supplying the heater or the contacts is faulty, so the part is simply de-energized.
  3. The control module itself or its firmware is faulty, therefore, it does not see a functioning heater.

These are serious reasons. If error 15 occurs, the machine may continue to work, but it does not satisfactorily wash the dishes. You should not leave everything as is, we will begin inspection and repair.

We check TEN

TEN dishwashers AristonHotpoint Ariston dishwashers have instantaneous heating elements. This is a large part adjacent to the circulation unit. Water passing through it is heated to the desired temperature and the machine can wash dishes with hot water due to this, increasing the washing efficiency. In order to get to the heater, you need to remove the lid of the pan of the dishwasher, after which the heating element will be at hand.

  1. We unhook and check the wires of the heating element with a multimeter.
  2. Check the resistance of the heater.
  3. Check the housing of the heater for damage and debris.

Quite often, the heater is so clogged that water through it ceases to circulate normally. This also affects the heating.

If you find problems with the heating element, do not try to repair it, this is useless. The item must be replaced. Its average cost is about $ 70. In order to remove the old heater and put a new one, you need to loosen the clamps. The wiring to the new heater must be connected in the correct sequence, so take a picture of how the old heating element is connected.
