Picked this up because the original component had worn out over time. Took around thirty minutes from start to finish. Appliance has been running normally since then. Repair turned out easier than expected honestly.

The appliance suddenly stopped working properly on our appliance ended up being caused by a failing part. Fitment on our appliance was accurate and the replacement solved it.

Installation wasnt too difficult overall while replacing the old component because the appliance suddenly stopped working properly. No leaks or issues noticed so far.
