Diagnosis

Where is the water coming from?

Leaks at the front usually mean a worn door gasket or damaged latch. Leaks underneath during the drain cycle point to a cracked pump housing or loose hose. Overflowing during fill means a faulty inlet valve or float switch.

Worn Door Gasket

The rubber seal around the door edge keeps water inside the tub during the wash cycle. It hardens and cracks over years of heat exposure, especially at the bottom corners where water pools during the cycle.

Signs this is the cause: puddle specifically at the front of the dishwasher, visible cracking or gaps when you inspect the gasket by hand.

Typical repair cost: $100 – $200

Damaged Door Latch

If the latch doesn't pull the door fully flush against the gasket, water sprays past the seal during the wash cycle. A door that feels loose or doesn't click firmly shut is a sign.

Typical repair cost: $100 – $200

Cracked Pump Housing

The pump housing sits at the bottom of the tub. Age and mineral buildup, common with Petaluma's water, can crack the housing or its seals, leaking water underneath the machine during the drain cycle.

Signs this is the cause: puddle appears specifically during or right after the drain portion of the cycle.

Typical repair cost: $150 – $300

Loose or Cracked Drain Hose Connection

The hose connecting the dishwasher to the drain can loosen at its clamp or crack from age, leaking at that joint.

Typical repair cost: $80 – $150

Faulty Water Inlet Valve or Float Switch

The float switch is meant to stop the tub from overfilling. If it fails, or if the inlet valve doesn't shut properly, the tub overflows during the fill portion of the cycle.

Signs this is the cause: leak happens specifically during the fill stage, before the wash cycle starts.

Typical repair cost: $100 – $250

Before You Call

What to check first

Note exactly when the leak happens.

During fill, during wash, or during drain. This single detail narrows the diagnosis significantly before we even arrive.

Check the door gasket by hand.

Run your finger around the full perimeter feeling for stiff, cracked, or torn sections, especially at the bottom corners.

Stop running the dishwasher until it's fixed.

A dishwasher leak under the cabinet floor often isn't visible until the floor is already warped.

FAQ

Dishwasher leaking, questions

No. A leaking dishwasher can damage the floor, subfloor, and cabinets quickly. A small leak under the tub often goes undetected until the cabinet floor is already warped.

Sudden, accidental leaks are often covered. Slow leaks from long-term wear, like a worn gasket, are frequently excluded. Check your specific policy.

A leak that happens only during fill, wash, or drain points to a specific component tied to that stage of the cycle, rather than a constant structural issue.

As soon as possible. Cabinet floors under dishwashers are especially vulnerable since leaks often go unnoticed until the wood has already absorbed water.
