If the heating element is intact as you say and shows in ohms, within 25 - 35 ohms, then pay attention to the thermal fuse with bimetallic contacts, usually a pair, through one pair there is a phase through the other zero. The fuse can be built into the casing of the heating element, or as a separate element near the heating element, on the bottom of the dishwasher. As a rule, one of the pairs of contacts burns out - the bimetallic plates themselves, but the other pair remains working and in good condition. If possible, you can change it, or you can short-circuit the burnt-out contact, tin it with tin and put flux on it, apply a brass strip to the edges of the contacts, press it with an overheated soldering iron and wait until the tin is evenly distributed over the contacts and the plate; another pair of working contacts will work for a long time.

Also look at the water pressure sensor - (rubber membrane combined with a contact switch), it is built into the rubber pipe that comes out of the steel pipe of the heating element, if you have this version of the heating element. All PMMs have the ONE PRINCIPLE OF OPERATION CYCLES. When the main motor turns on, it supplies water under pressure to the impellers of the dishwasher. As a result of the resulting water pressure, the pressure sensor is triggered and with its contacts connects the power supply circuit of the heating elements.

Also look at the triacs on the control board, one of them can also switch the power supply to the heating element. PS: even the same model of dishwasher, but produced in different years, has differences in the electrical actuators and components, so I described to you different variants of components, which ones you might have?!

The heating element of the electrolux esf 9451 low dishwasher does not heat the water.
I checked the input voltage to the heating element, only 55 volts
