What 700197 means on a Cove dishwasher

Error code 700197 on a Cove dishwasher corresponds to fault designation PE1, which indicates the pressure sensor detected an overfill condition during an active wash cycle. The pressure sensor monitors water level inside the tub continuously throughout the wash program. When water rises beyond the acceptable threshold, the control board interprets this as an overfill event and halts the cycle to prevent water from escaping the unit or damaging internal components.

The pressure sensor in Cove dishwashers uses a pneumatic or electronic pressure detection system to read tub water levels in real time. An overfill fault can be triggered by an actual excess of water entering the tub, but it can also result from a sensor or hose that is providing inaccurate readings. Blockages in the pressure sensor port or air trap, a kinked or disconnected pressure hose, or a faulty sensor element can all cause the control board to register a false overfill signal even when the actual water volume is within normal range.

Additional causes include a malfunctioning water inlet valve that fails to close fully, allowing water to continue entering the tub beyond the fill target. Excess suds from using the wrong detergent type or too much detergent can also fool the pressure sensor into reading a higher water level than actually exists. The recommended first diagnostic step is to empty the dishwasher of all dishes and run a Rinse/Hold cycle to observe whether the fault reappears under a controlled, low-load condition.

Common causes of 700197

  1. 01

    Excess suds from improper detergent

    Wiring / connection

    Using a non-dishwasher detergent or too much detergent produces heavy foam that the pressure sensor can misread as an overfill condition. Check for visible suds inside the tub and switch to the correct detergent type in the recommended amount.

  2. 02

    Faulty or stuck water inlet valve

    Part replacement

    A water inlet valve that does not close fully allows water to keep flowing into the tub past the intended fill level. If the tub is visibly overfilled with standing water after the cycle stops, the inlet valve is a likely culprit and will need replacement.

  3. 03

    Blocked or disconnected pressure sensor hose

    Wiring / connection

    The hose connecting the pressure sensor to the air trap can become kinked, clogged, or disconnected, causing the sensor to register an inaccurate water level. Inspect the hose for obstructions, damage, or loose connections at both ends.

  4. 04

    Faulty pressure sensor

    Part replacement

    A failed pressure sensor element can send incorrect voltage or resistance readings to the control board, triggering a false overfill fault even when the actual water level is normal. If all other causes are ruled out, the sensor itself should be tested and replaced if readings fall outside spec.

  5. 05

    Drain system restriction causing water backup

    Wiring / connection

    A clogged filter, blocked drain hose, or restricted garbage disposal connection can prevent water from draining properly between fills, causing cumulative water buildup that triggers the overfill sensor. Clean the filter and check the drain path for obstructions.

Frequently asked questions about 700197

What does 700197 mean on a Cove dishwasher?
Error code 700197 corresponds to fault code PE1, which means the pressure sensor detected an overfill condition during an active wash cycle. The dishwasher halted the cycle automatically to prevent water overflow or internal damage. The cause can be an actual excess of water in the tub or a faulty sensor giving a false high-water reading. Starting diagnostics by emptying the unit and running a Rinse/Hold cycle helps determine whether the fault is load-related or mechanical.
How do I fix error code 700197 on my Cove dishwasher?
Begin by removing all dishes from the unit and running a Rinse/Hold cycle to see if the fault reappears. Check for excess suds inside the tub, which can trigger a false overfill reading, and verify you are using the correct dishwasher detergent in the proper amount. If the error persists, inspect the drain filter and drain hose for blockages, and check the pressure sensor hose for kinks or disconnections. If those steps do not resolve the issue, the water inlet valve or pressure sensor may need to be tested and replaced.
Is it safe to use my Cove dishwasher when error 700197 is showing?
You should not continue running normal wash cycles while this error is active, as the overfill fault indicates water may be reaching an unsafe level inside the tub. Running the machine in this condition risks water escaping the unit and causing floor or cabinet damage. Use the Rinse/Hold cycle as a diagnostic test only, and resolve the underlying cause before returning the dishwasher to regular use.
Will resetting my Cove dishwasher clear error code 700197?
A power reset may clear the error code temporarily, but it will not fix the underlying cause of the overfill fault. If the condition that triggered PE1 is still present, the error will return during the next wash cycle. It is important to diagnose and correct the root cause, whether that is a detergent issue, a blocked drain, or a component failure, before the reset will result in lasting normal operation.
How much does it cost to repair a Cove dishwasher showing error 700197?
Repair costs vary depending on the cause. If the fix is simply switching to the correct detergent or cleaning a blocked filter or drain hose, there may be no parts cost at all. Replacing a water inlet valve or pressure sensor typically involves parts costs in the range of $30 to $150 depending on the component, plus labor if a technician is required. Cove dishwashers are premium appliances, so sourcing brand-specific parts may place costs toward the higher end of that range.
