Whirlpool Washer Error Code 1

Error code 1 on a Whirlpool washer means the drain cycle took longer than 6 minutes to complete. The control board monitors drain time and flags this fault when water is not evacuated within that threshold. The three most common causes are a failed drain pump, a faulty pressure switch medium level contact, or a blocked or incorrectly routed outlet hose. A technician can run the Service Routine to perform a controlled drain test and isolate the exact cause.

It is not advisable to continue running the washer with an active drain fault. If water is not evacuating properly, the machine may leave standing water in the tub, which can lead to mold growth and unpleasant odors. Running the motor and pump repeatedly against a blocked or failed system can also cause additional wear. Resolve the drain issue before resuming normal laundry cycles.

Repair costs vary depending on the cause. Clearing a hose clog or cleaning the pump filter is essentially free if done yourself. A replacement drain pump typically costs between $30 and $80 for the part, with labor adding $100 to $200 if a technician is doing the work. A replacement pressure switch generally runs $15 to $50 for the part. Diagnostic service calls to identify the cause usually range from $60 to $120 depending on your area.

Some causes of this error are DIY-friendly. Checking the outlet hose for kinks, clogs, or a routing height above 72 inches requires no special tools and no parts. Cleaning the pump filter or inlet is also straightforward on most models. However, replacing the drain pump or pressure switch involves disassembly and electrical component handling, which is better suited to a technician if you are not comfortable with appliance repair.

A reset may temporarily clear the error code from the display, but it will not resolve the underlying problem. If the drain pump, pressure switch, or hose routing issue is not corrected, the code will return as soon as the washer attempts another drain cycle. Address the root cause first, then confirm the repair by running a full cycle or the Service Routine drain task.
