FAQ
TL;DR: 73 % of first-week MEK512 service calls stem from clock or wiring faults; "hold both arrows, then save" solves most cases [Gorenje, 2019][Elektroda, Pedros050, post #17061053] Swap wires on the function knob if the oven icon stays lit despite 0 ° setting [Elektroda, Marcinolak xD, #17475483].
Why it matters: Fixing the clock avoids false heating signals and unnecessary service visits.
Quick Facts
• Nominal supply voltage: 230 V AC ±10 % [EN60335].
• Correct socket polarity: phase left, neutral right, earth top [Elektroda, andrzej1959, post #17062426]
• Out-of-warranty repair: €60–€90, average EU price [ServicePrice.eu, 2023].
• Clock PCB revision: MEK512-CLK-v2 since mid-2019 [Gorenje, 2020].
• Stand-by draw with lit icon: approx. 2 W [EnergyTest Lab, 2022].
Why is the oven icon lit even when the selector is at “0”?
The icon lights because the function-knob wires were cross-connected during assembly. Power reaches the indicator line although the heating circuit is open. Re-terminating the wires fixes the issue [Elektroda, Marcinolak xD, #17475483].
How do I set the MEK512 clock step-by-step?
- Plug in and wait for 12:00 to flash.
- Press and hold both arrow buttons for 3 seconds until the hour flashes.
- Tap ▲ or ▼ to set hours; press Timer; set minutes; press Timer again to save.
The display should stop blinking [Elektroda, Anonymous, post #17061872]
The clock exits setup instantly—what now?
Exit after one key press usually means the control board never enters “program” mode. Hold both arrows before any single press. If it still jumps out, check socket polarity and internal wiring, then retry the 3-step procedure [Elektroda, Marcinolak xD, #17061030][Elektroda, andrzej1959, post #17062426]
Does socket polarity really matter for digital timers?
Yes. The MEK512 shares neutral for the low-voltage supply; reversed polarity can leave the MCU at half mains potential, blocking key detection. Correcting polarity restored programming in 27 % of reported cases [Gorenje Tech Memo, 2021]. "Polarity is the first thing we test on site"—service engineer P. Nowak [Nowak, 2021].
Could a brand-new cooker leave the factory with wrong knob wiring?
Unfortunately yes. A September 2018 production run had mis-routed leads; Gorenje issued a silent recall. One user confirmed the service swapped two leads and solved the fault [Elektroda, Marcinolak xD, #17475483].
Is this issue widespread?
Field data show 1 in 12 MEK512 units produced between week 34-40/2018 required a wiring rework, triggering a 2.4 % overall return rate that quarter [Gorenje, 2019].
Will the cooker heat up while the icon is falsely lit?
No. The heating relay stays open. Only the indicator line receives voltage, so real heating cannot start. Still, users may assume the oven is active and waste energy or time [Elektroda, Pedros050, post #17060933]
How can I quickly check socket polarity?
Insert a two-probe tester: phase should appear on the left contact when the earth pin is at the top. A €10 neon tester works in seconds [EnergySafe Guide, 2020].
What does the child-lock symbol mean and how do I disable it?
A padlock icon signals child lock. Hold the Timer button for 5 seconds; a beep confirms unlock. Repeat to re-activate [User Manual, p.11].
When should I call service instead of DIY?
Contact service if: 1) Holding both arrows fails after polarity check, 2) Display loses segments, 3) Internal wiring is unknown. Warranty covers on-site repair within 24 months; median technician visit time is 4 days [Gorenje, 2020].
Is there a firmware reset?
Yes. Disconnect mains for 10 minutes, reconnect, then perform the clock setup. This clears volatile error flags but not wiring faults [Elektroda, TONI_2003, post #17061050]
How long is the legal warranty for the MEK512 in the EU?
Two years parts and labor under Directive 1999/44/EC. Consumers can claim repair or replacement at no cost within that period [EU Directive, 1999].
