Why your LG dishwasher is not heating
When a LG dishwasher is not heating, here's what you'll usually notice: appliance runs but doesn't reach set temperature. Failed heating element, igniter, or thermal fuse. On this platform it's most often tripped thermal fuse. Left unaddressed, laundry backs up fast.
Most likely causes
- Tripped thermal fuse
- A bad control board
- Failed igniter or gas valve
Known LG dishwasher weak points
- Linear compressor cooling failure (class-action litigation)
- Front-load drum bearing wear causing grinding/rumble
- Recurring UE unbalanced-load errors on washers
- Water and ice dispenser malfunctions
Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: check whether an ignition click or spark is audible at all when it should be heating. Also, confirm the dishwasher has power, any gas supply valve is open, and a simple reset — power off 60 seconds, back on — doesn't restore heat. If none of that changes anything, no spark or flame usually means the igniter or gas valve itself has failed, and gas-carrying parts are restricted to licensed work in most jurisdictions.
How we fix it
An experienced tech tests the LG dishwasher systematically and pinpoints what's actually causing the not heating. Genuine LG OEM parts are widely available through authorized distributors, but sealed-system refrigerant repairs (including linear compressors) require an experienced technician. The quote is flat, approved before we start, and every repair carries our warranty.
