Repair Outcome

Access was a little tight behind the panel while replacing the old component because the small leak developed near inlet section. Appliance has been running normally since then.

Helpful Product Insight

Fitment on our appliance was accurate while replacing the old component because the water flow became inconsistent. Appliance has been running normally since then.
