LEXTON LX U02 Programmer Not Cutting Power to 1700W Cooker in AUTO Mode

Hello,

I have a LEXTON LX U02 time programmer. For some time now, in AUTO mode, the programmer does not cut the current to the accumulation cooker when it should. In MANUAL OFF mode it also sends out the current. When I connect a regular light, the programmer works as it should. The power rating of the cooker is 1700W and the programmer according to the manufacturer has a maximum load of 16A/3600W. What could be wrong? I'm a layman so most likely won't fix it. What else could I buy?

Greetings.

A little distance from these parameters of the programmer! Without going into details, buy a new programmer, a contactor with a 230V coil, let the programmer switch the coil of the contactor, the contactor switch the power supply of the cooker and that's it. Greetings!
