Electrolux Oven Error Code Htd

The Htd code means the drain temperature sensor, designated NM8, has detected a temperature above the 115 degree Celsius safety limit in the drain system. The oven shuts down automatically when this threshold is reached to protect components. The most common reason is that the drain syphon has run dry, removing the water that normally keeps the probe cool. Refilling the drain syphon with water from a jug is the recommended first diagnostic step.

No. The Htd code causes the oven to stop operation automatically precisely because continuing to run with drain temperatures above 115 degrees Celsius poses a risk of damage to drain components and plumbing. Do not attempt to bypass the fault or force the machine to continue operating until the underlying cause has been identified and corrected.

If the issue is only a dry syphon, there is no parts cost at all, just the time to add water to the drain trap. If the NM8 drain temperature probe has failed and needs replacement, repair costs including parts and labor typically range from around $100 to $300 depending on parts availability and local labor rates. A service call alone to diagnose the fault generally runs between $75 and $150.

Start by carefully pouring water into the drain syphon to refill the pipe and allow the NM8 probe to cool down. Once the syphon has water in it and the oven has had time to cool, attempt to restart the unit. If the Htd fault returns after the syphon is confirmed full of water, inspect the drain assembly for blockages and test the NM8 probe and its wiring for faults.

A simple power reset may temporarily clear the display, but the Htd code will return if the underlying condition, typically a dry syphon or a faulty NM8 probe, has not been addressed. You should refill the drain syphon with water and allow the probe to cool before resetting the unit to give the reset the best chance of holding.
