What a GE Dishwasher Total Tub Failure Looks Like — and What to Do

A total tub failure on a GE dishwasher is one of the more dramatic appliance failures you’ll encounter — and knowing what it looks like can save you from a flooded kitchen. In this short video, we show you exactly what this failure mode looks like in real life.

What Is a “Total Tub Failure”?

A total tub failure means the inner tub of the dishwasher — the plastic or stainless steel chamber that holds water during the wash cycle — has cracked, corroded through, or separated at a seam. Water no longer stays inside the tub during operation. Instead, it leaks directly onto the floor or into the cabinet below. Most dishwasher leaks aren’t this serious — a worn door seal or stuck float switch is far more common, so check the usual leak causes first.

Warning Signs Before a Full Failure

• Small puddles under or around the dishwasher after a cycle
• Water stains or warping on the cabinet floor under the unit
• Rust streaks on the inside tub walls or around the door seal
• Visible crack or pit in the inner tub — usually near the bottom
• Musty smell under the dishwasher

Common Causes

• Rust and corrosion — especially in older plastic tub models
• Hard water mineral buildup that erodes the tub lining over time
• Impact damage from heavy pots or dropped items inside the tub
• Manufacturing defect in early-production models (GE issued advisories on some GDT/GDF series)
• Age — dishwashers over 10–12 years old are at higher risk

Can It Be Repaired?

In most cases, a total tub failure is not cost-effective to repair. Replacing an entire dishwasher tub requires near-complete disassembly, and replacement tubs are often discontinued or priced close to a new unit. Small hairline cracks can sometimes be temporarily patched, but this is not a permanent fix. Our honest recommendation: if the tub has failed, it’s time to replace the dishwasher. The 50% rule explains why.

What to Do Right Now

If you suspect a tub leak, stop using the dishwasher immediately. Water leaking under the unit can damage your flooring, subfloor, and cabinetry — turning a $500 dishwasher problem into a $3,000 floor repair. Turn off the water supply line to the dishwasher (under the sink) until you can get it inspected. If the water is pooling inside the tub instead of under it, that’s usually a drain problem — see dishwasher not draining.
