Frequently Asked Questions

Can I use vinegar to clean the dishwasher drain?expand_more

Yes, running a cup of vinegar in an empty cycle helps dissolve grease and odors, but it won't remove solid clogs.

Why does my dishwasher drain slowly?expand_more

A partial clog in the filter or drain hose reduces flow. Clean both components to restore normal drainage.

What if the drain hose is frozen?expand_more

If the hose runs through an unheated area, it can freeze. Thaw it with a hairdryer or warm towels.

Should I call a pro if the dishwasher still won't drain?expand_more

If you've cleaned the filter and hose and it still won't drain, the drain pump may be faulty. Call a technician.
