Washer & Dryer Stackable Repair in San Francisco’s Sunset District: Clearing a D90 Error
Our technician was recently called to a home in San Francisco’s Sunset District to service a stackable washer and dryer unit. The customer reported that the dryer was showing a persistent D90 error code, which usually points to an airflow restriction. Upon inspection, our technician quickly discovered that the vent line was completely clogged.
A thorough cleaning was performed, during which an unexpected object was found lodged deep inside the vent line. It was unclear whether the obstruction was a small pillow or a wallet that somehow made its way into the vent. Along with that, numerous coins were also retrieved from the line. This blockage was the root cause of the D90 error and was compromising the efficiency and safety of the dryer.
Once all obstructions were removed and the vent line was fully cleared, the stackable unit was tested and returned to optimal working condition. The entire job was completed on the same day for $300, much to the customer’s relief.
