We highly recommend Parker & Sons to anyone who will need an appliance repaired. They were quick to respond to our needs, notifying us of their arrival time and then fixed our dishwasher. It runs beautifully. Bob, our repairman was professional, knowledgeable and courteous.

Dishwasher Installation questions, answered by experts

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.

Your first instinct might be to grab the bleach to clean a moldy dishwasher, but it’s not the best product for the job. You don’t want to use bleach to clean stainless steel components if your dishwasher has them, as it can cause significant damage. In addition, the scent of bleach can linger if not rinsed well, causing your dishes to retain a smell (and even taste) of bleach.

Basic maintenance, such as cleaning filters, is DIY-friendly, but repairs involving electrical components, pumps, or valves should be handled by a professional.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.
