What 800115 means on a Cove dishwasher

Error code 800115 on a Cove dishwasher indicates that the unit's pressure sensor has detected a draining problem. The pressure sensor monitors water levels inside the dishwasher tub, and when it detects that water is not evacuating as expected during or after a drain cycle, it triggers this fault code. The control board uses this sensor feedback to confirm that the tub has reached an appropriately low water level before advancing to the next wash phase or ending the cycle.

The most common sources of this error are physical obstructions in the drain path. This includes a clogged or restricted air gap at the sink, a kinked or blocked drain hose inside or outside the unit, and incorrect drain line routing such as a hose that lacks a proper high loop or is connected improperly to the sink drain or garbage disposal. A particularly frequent installation oversight is failing to remove the knockout plug from a newly installed garbage disposal, which completely blocks water from draining into the disposal inlet.

Because the fault is detected by the pressure sensor rather than a direct flow sensor, any condition that prevents adequate water removal from the tub can trigger code 800115. This includes a faulty or obstructed drain pump, a pinched drain hose behind the dishwasher, or debris accumulation in the sump area. Addressing the error requires methodically inspecting the entire drain path from the sump and pump through the hose routing and all the way to the drain connection point at the sink or disposal.

Common causes of 800115

  1. 01

    Garbage disposal knockout plug not removed

    Wiring / connection

    When a dishwasher is connected to a newly installed garbage disposal, a factory knockout plug inside the disposal inlet must be removed before use. If this plug is still in place, water has nowhere to drain and the pressure sensor will immediately detect the failure.

  2. 02

    Clogged or blocked air gap

    Wiring / connection

    The air gap fitting mounted on the countertop or sink deck can accumulate debris and become restricted, preventing proper water flow out of the dishwasher. Removing the air gap cap and cleaning out the interior often resolves this quickly.

  3. 03

    Drain hose kink or blockage

    Wiring / connection

    The drain hose can become kinked behind the dishwasher or clogged with grease and food debris along its length. Pulling the unit out slightly and inspecting the hose for bends, clogs, or improper routing will help identify this issue.

  4. 04

    Incorrect drain line routing

    Wiring / connection

    The drain hose must be routed with a high loop or standpipe connection to prevent backflow and ensure proper siphoning during the drain cycle. A hose routed too low can allow water to re-enter the tub or drain sluggishly, triggering the pressure sensor fault.

  5. 05

    Faulty or obstructed drain pump

    Part replacement

    If the drain pump impeller is jammed with debris such as broken glass, food particles, or small objects, the pump cannot move water out of the sump. A failed pump motor will also produce this code and would require a replacement pump assembly.

Frequently asked questions about 800115

What does 800115 mean on a Cove dishwasher?
Error code 800115 means the dishwasher's pressure sensor has detected that the unit is not draining properly. The sensor monitors the water level in the tub and triggers this fault when water fails to evacuate as expected during a drain cycle. The issue is typically located somewhere along the drain path, from the sump and drain pump through the hose and into the sink or garbage disposal connection.
How do I fix error code 800115 on my Cove dishwasher?
Start by checking the air gap on your sink for blockages and clear it if needed. Next, verify that the knockout plug has been removed from your garbage disposal inlet if the disposal is new. Inspect the drain hose for kinks or clogs and confirm it is routed with a proper high loop. If those steps do not resolve the error, the drain pump sump area may need to be inspected for debris or the pump itself may need to be tested or replaced.
Is it safe to use my Cove dishwasher while error 800115 is active?
It is not recommended to continue running the dishwasher while this error is present. If water is not draining correctly, running additional cycles can cause water to accumulate in the tub and potentially overflow onto the floor. Resolving the drain issue before resuming use will prevent water damage and protect the appliance.
Will resetting my Cove dishwasher clear error code 800115?
A power reset may temporarily clear the error code, but the fault will return if the underlying drain obstruction or installation problem has not been corrected. The pressure sensor will detect the same draining failure on the next cycle and trigger the code again. The drain path must be physically inspected and corrected for the error to stay resolved.
How much does it cost to repair a Cove dishwasher showing error 800115?
If the cause is a blocked air gap, kinked hose, or an unremoved disposal knockout plug, the repair can often be done at no cost beyond your time. If a service technician is needed to diagnose and clear a drain hose blockage or sump obstruction, labor costs typically fall in the range of $100 to $200. Replacing a failed drain pump, if that is the root cause, generally adds $150 to $350 in parts and labor depending on your location and service provider.
