Good evening.

Dishwasher Indesit DFP 5847​

We have the following problem((

We bet on a certain mode, we start. The display shows a washing time of 2.25 hours. It washes for about five minutes, then the time suddenly drops by an hour, the water does not heat up. And as a result, the dishes are not washed properly ((Until today, they set it to the not full load mode, the main thing is on this mode washes as it should, and heats the water to the appropriate temperature. But this evening I set it to the same mode, incomplete load, there, too, both time and heating began to go wrong. Please tell me what could be the problem? We searched the entire Internet, nothing found. We bought the car a few days ago, and this is the problem from the first days (((
