# Would this buildup cause “dHE” error on an LG Tromm dryer?

Got the machine off craigslist. During the drying cycle it stops and shows the error.

The user manual tells that with dHE error I should inspect the water supply, if the water supply is within spec, call service.

The service manual says it means "Dry heater error" and list this:

The Dry Heater is out of order.
- Replace the Dry Heater
• The connector of the Dry Heater is not connected
properly to the connector in the main PWB ASSEMBLY.
- Reconnect or repair the cannector.(sic)
• The Dry Fan Motor is out of order.
-Replace the fan motor.


Following the steps for each of the diagnostics, There's one step saying to open the motor propeler for the dry-heater assembly and check for foreign objects that may be impacting the rotation.

I didn't find any object per-se, but there is a lot of buildup there. Is it worth cleaning this up, testing, drying the machine again, or investigating further directly? I have zero experience with appliances.

I can't check if it impact the spinning while closed very well, as i can't turn it.
