Newly installed dishwasher not working right

Symptoms

• Problems begin immediately after a new install
• Leaking, no power, or no water are the main symptoms
• Installer or DIY install was recent
• Everything seemed fine during a quick installer test but issues appeared later

Likely causes

• CommonWater supply valve not fully opened after installInstallers sometimes leave this only partially open, or it gets bumped closed.
• CommonShipping bolts, brackets, or foam blocks not removedSome dishwashers ship with an internal bracket or the tub braced for transit that must be removed before use.
• CommonLoose electrical or plumbing connection from installationA newly made connection is more likely to be slightly loose than one that's been in place for years.
• PossibleDrain hose high-loop or air gap not installed correctlyImproper drain hose routing during install can cause draining problems from day one.
• Less commonGenuine manufacturing defectOccasionally a new unit does have a factory defect, which is what the warranty covers.

What to do

1. Confirm the water supply valve under the sink is fully open, not just cracked.
2. Check the installation manual for any shipping brackets, tape, or foam that must be removed before first use, especially around the tub or motor.
3. With power off, check that the water line and drain hose connections are snug and not just finger-tight.
4. Verify the drain hose has a proper high loop or air gap as specified for your setup to prevent backflow and drainage issues.
5. Check the electrical connection (plug or hardwired junction box) for a secure connection.
6. If everything checks out but problems continue, contact the installer or manufacturer, since a new unit is typically still under warranty.

Tools and parts

• Screwdriver
• Adjustable wrench

When to call a pro

For a newly installed unit, contact the installer or manufacturer first since the problem is likely installation-related and may be covered under warranty.
