JAY - For model number WTW4850XQ1
July 22, 2026
What motor starting capacitor is used on Model WTW4850XQ1 washer? Washer stopped in middle of cycle. Would not start. After cleaning the machine, it not restart. What is the most likely cause?
Chris Boyle Profile
Hello Jay, thank you for contacting us. The motor run capacitor for your washer is part number PS11703495. The most likely cause of the mid-cycle shutdown and failure to restart, the lid lock assembly could be failing. The lid lock must send a continuous signal to the control board confirming the lid is secured during agitation and spin. If the lock mechanism or strike fails, the washer stops immediately as a safety precaution and will refuse to restart. If the lid lock looks intact, the main control board may have locked up from a voltage fluctuation during the mid-cycle shutdown. Try a hard reset by unplugging the washer for 5 to 10 minutes then restoring power. If the unit remains completely unresponsive after the reset, the main control board, part number PS4704636, may need to be replaced. Glad to be of assistance!

washer wouldn't agitate
955 of 1057 people found this instruction helpful.
  • mike from Kent, WA
  • Easy
  • 15 - 30 mins
  • Screw drivers, Socket set
First pry off the cap of the agitator. Then using a socket remove the bolt that holds the plastic cup in place. Remove this cup by prying it loose from the two tabs that hold it in place. Once this cup is removed you can get to the broken cogs.
Slip the new cogs into the underside of the cup, and slide the cup back down in the a gitator housing using the slots on the side for a guide. (You may want to remove the entire agitator and assemble everything upside down, then flip it all back over to mount, so the cogs don't fall out).
Tighten the bolt, snap the cap back in place on top of the agitator and your'e done. Easy repair.

Lid Lock light blinking, machine will not start
324 of 404 people found this instruction helpful.
  • David from Los Alamos, NM
  • A Bit Difficult
  • 30 - 60 mins
  • Nutdriver, Screw drivers
A detailed Service Technician Service Manual is hidden inside the machine on the front panel. It is hidden by the bleach dispenser input. It gives a list of fault codes and instructions for calibration after repair, resetting fault codes, and a manual test mode for stepping the machine through each mode on command. The Tachometer faile d which would not let the machine come up to maximum spin speed. The tachometer is part of the solenoid actuator that shifts the transmission. It is not specifically called out in the manual. Any failure causes the lid lock light to blink which gives the appearance of a lid lock failure
