Repair planning
E3 cost planning: The published isolation or cooldown check costs €0. A qualified heating-system diagnosis is generally planned within €90–€220 before parts; request separate heater, sensor, wiring, labor, and call-out lines.
E3 time plan: 5–15 minutes for the E3 safety check, plus any documented cooldown; a qualified heating-system diagnosis commonly takes 30–90 minutes before repair.

E3 parts decision: E3 points to the dishwasher did not reach the required temperature because of a heating-element malfunction, but it does not prove whether the heater, relay, sensor, wiring, circulation system, or control is responsible. Order only the exact-model part confirmed by diagnosis.
What not to do
- Do not repeat heating cycles, bypass thermal protection, test a live heater or relay, or order a heater from E3 alone
- Do not run an extra test cycle after the source tells you to stop or arrange service for E3
Preventive maintenance
- 1Follow the exact Beko maintenance schedule for the dishwasher and keep the model, serial number, and service history available
- 2If E3 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
