Repair Note
5
Connector alignment matched better than expected while replacing the old component because the older unit needed replacement part. No leaks or issues noticed so far.

Replacement Observation
5
Picked this up cause the original component had worn out over time. Access was a little tight behind the panel. Unit completed a full cycle without issues. Worth verifying model number before ordering though.
