What 570114 means on a Cove dishwasher

Error code 570114 on a Cove dishwasher corresponds to fault designation FLT2, which signals that the salt level in the water softener regeneration tank has dropped below the minimum threshold. Cove dishwashers equipped with integrated water softening systems use ion exchange resin to reduce water hardness. This resin requires periodic regeneration using dishwasher-specific salt (sodium chloride), which flushes accumulated calcium and magnesium ions from the resin bed. When the salt reservoir falls too low, the softener cannot regenerate effectively, and the appliance triggers this fault to alert the user before water quality is compromised.

The regeneration tank is a separate compartment, typically located beneath the lower spray arm and accessed by removing the floor of the dishwasher interior. A sensor or float mechanism monitors the salt level and communicates with the control board. When the salt concentration or physical level drops below the operational minimum, the FLT2 code is generated and displayed. The User Interface Module (UIM) will also present on-screen guidance to assist with the refill procedure, so following those prompts is the recommended first step.

This fault is not indicative of a component failure in most cases. It is a maintenance alert designed to protect both the water softening resin and the dishwasher's internal components from hard water scale buildup. Using the wrong type of salt, such as table salt or rock salt, can cause bridging or caking in the reservoir and may prevent the sensor from reading correctly even after a refill.

Common causes of 570114

  1. 01

    Salt reservoir depleted

    Wiring / connection

    The most common cause is that the salt supply in the water softener compartment has been consumed through normal regeneration cycles. Refilling with dishwasher-grade salt and following the UIM prompts will resolve the error.

  2. 02

    Salt bridging or caking

    Wiring / connection

    Salt can clump together and form a hardened bridge inside the reservoir, leaving the area near the sensor empty even when salt remains above. Breaking up the caked salt and refilling as needed typically resolves this.

  3. 03

    Incorrect salt type used previously

    Wiring / connection

    Table salt, rock salt, or other non-dishwasher-grade salts can dissolve unevenly and leave residue that interferes with the salt level sensor or clogs the reservoir. The compartment may need to be flushed and refilled with the correct product.

  4. 04

    Salt level sensor or float malfunction

    Part replacement

    If the error persists after a confirmed proper refill, the float or sensor mechanism that monitors salt level inside the tank may be stuck or faulty. This would require inspection and possible component replacement.

  5. 05

    Reservoir cap not sealed properly

    Wiring / connection

    A loose or improperly seated salt reservoir cap can allow water to dilute the salt concentration more rapidly than normal, triggering the low-salt alert sooner than expected. Inspect and tighten the cap after each refill.

Frequently asked questions about 570114

What does 570114 mean on a Cove dishwasher?
Error code 570114 corresponds to fault FLT2, which means the salt level in the built-in water softener regeneration tank is too low. The dishwasher uses this salt to regenerate its ion exchange resin and maintain effective water softening. This is a maintenance alert, not a mechanical failure. Adding dishwasher-specific salt and following the on-screen UIM instructions will typically clear the fault.
How do I fix error code 570114 on my Cove dishwasher?
Open the salt reservoir compartment, located in the floor of the dishwasher tub, and refill it with dishwasher-grade water softener salt. Follow the step-by-step instructions shown on the User Interface Module display. Once the salt is added and the cap is securely replaced, run the dishwasher to allow the system to register the new salt level and clear the fault.
Is it safe to run my Cove dishwasher when error 570114 is showing?
Operating the dishwasher with low softener salt will not cause immediate damage to dishes or create a safety hazard, but it does mean the water softening system is not functioning at full capacity. Over time, hard water can cause scale buildup on internal components and on dishes. It is best to refill the salt as soon as possible to maintain proper performance.
Will resetting my Cove dishwasher clear error code 570114?
A simple power reset will not permanently clear error code 570114 because the underlying condition, low salt level, has not been corrected. The fault will return once the control board checks the salt level sensor again. The correct fix is to add the appropriate dishwasher-grade salt to the regeneration tank and follow the UIM prompts.
How much does it cost to fix error 570114 on a Cove dishwasher?
In most cases, the only expense is the cost of dishwasher water softener salt, which typically runs between $5 and $20 depending on the brand and quantity purchased. If the salt level sensor or float mechanism is found to be faulty and requires replacement, parts and labor costs could range from $75 to $200 or more depending on service rates in your area.
