COMPONENTS
Drain pump
Drain pumps are mounted to sumps in the front of dishwashers
Pump specifications
Drain pump is rated 120V, 60 Hz, 35W, 0.85A.
Solving installation issues
Often improper installations, not drain pump issues, cause dishwashers to not drain properly.
Must have drain hoses with high loops (min. 20” high) or drains with air gaps.
Drain hoses are 6’ long and can be up to 10’ long.
Secure drain hoses to rear of dishwashers with
Make sure drain hoses aren’t kinked.
Cavitating
Cavitating may occur in any type of pump when impellers spin faster (from low inlet or outlet pressure), creating air pockets around impellers. Cavitating pumps can be noisy. Air gaps/high loops keep water contacting pump outlets, preventing air pockets from forming.
