Cove Dishwasher Error Code 800 140: Drain Pump Ran Too Long

Cove dishwasher error code 800 140 means the drain pump ran longer than the control allows while emptying the tub, so the Cove stopped the cycle instead of pumping against a restriction. Start by switching the dishwasher's breaker off for 30 seconds, then clear the drain path before a short test run.

On a first appearance, Cove error 800 140 is usually a drainage problem, not a dead pump. The Cove DW2451 Use and Care Guide ties a sister drain message, 800115, to four owner checks: drain line and air gap, disposal knockout, hose kinks and height, and the filter.

What does Cove code 800 140 actually mean?

The Cove control times every drain. If the sump water level does not fall in time, the Cove drain pump keeps running, and once that run passes its limit the dishwasher logs 800 140 and stops.

A Cove drain pump that times out is usually pushing against a blockage: a packed sump filter, a kinked hose, a clogged air gap or a sealed disposal inlet. Less often the Cove pump impeller is jammed by glass or a fruit pit. Standing water in the Cove tub after the code points to the drain path, not the electronics.

How do I reset Cove dishwasher code 800 140?

Step 1: switch off the breaker feeding the Cove dishwasher for 30 seconds.

Step 2: with power off, bail standing water from the Cove tub so the filter is reachable.

Step 3: do the Cove drain checks in the next section.

Step 4: restore power and run the shortest cycle, listening for the Cove drain pump. If 800 140 returns on that first drain, stop resetting; the Cove control is reporting a real restriction or a failing pump.

Which drain checks are safe for an owner?

Sump filter: with the breaker off, twist out the Cove filter, rinse it and scrub the mesh with a soft brush. Cove's 30 01 14 Clean Filter reminder exists because a greasy filter slows drainage.

Air gap: if a chrome cap sits beside the faucet, lift the cap and clear packed food underneath. Water spilling there while the Cove drains confirms the clog.

Disposal knockout: a new garbage disposal ships with a plug in its dishwasher inlet. Many post-1960 terraced ranch homes in the planned Moraga Valley have remodeled kitchens, so check any later disposal for a knockout left in before the Cove hose went on.

Hose route: follow the Cove drain hose under the sink; the hose must not be kinked, crushed by stored bottles, or more than 4 feet (1.2 m) above the dishwasher floor.

When does a Cove drain fault need a technician?

Book service when 800 140 returns after a 30-second breaker reset, a clean filter and a clear hose. The remaining causes sit beyond an owner's safe reach: a Cove drain pump with a broken impeller or tired motor, debris inside the pump housing, or a hose pinched behind the cabinet. Humming or grinding with no water moving points the same way.

A technician pulls the Cove dishwasher from its panel-ready opening and tests the drain pump directly. Moraga Sub-Zero Repair charges a $195 diagnostic fee, credited to the repair. A photo of the code and the Cove model label speeds the visit.
