D.I.Accessa W10195039 Float Switch – Reliable Single Replacement
Brand: D.I.Accessa
A reliable single float switch for common Whirlpool-family dishwashers.
The D.I.Accessa W10195039 float switch is a straightforward replacement for Whirlpool, KitchenAid, Maytag, Amana, Jenn-Air, and Inglis dishwashers.

Functionally, this switch works exactly as it should: if the water level exceeds the designated limit before the fill cycle finishes, it closes the water inlet valve to prevent overflow.

For a no-fuss, single-part fix, this is a dependable choice.

Parzuozenney WD21X10519 Flood Switch – Fixes Multiple Issues
Brand: Parzuozenney
A versatile flood switch that addresses multiple GE dishwasher problems.
The Parzuozenney WD21X10519 flood switch is designed to tackle the top three dishwasher problems: water overflow, incomplete cycles, and no-heat drying. That’s because it’s an integrated thermistor assembly, which means it not only monitors water levels but also helps with temperature sensing. If your GE dishwasher has been leaving dishes wet or stopping mid-cycle, this part could be the solution.
Durability is a key selling point here. The switch features a high-impact ABS plastic housing and corrosion-resistant terminals, so it can handle the humid environment inside a dishwasher without degrading quickly. Installation is a DIY-friendly task that takes about 15 to 20 minutes with standard tools like a 1/4-inch nut driver and a Phillips screwdriver. You can also find helpful installation videos on YouTube by searching for the part number. This switch is compatible with GE, Hotpoint, and RCA dishwashers, making it a versatile repair option.

Cykemo W10327249 & W10195039 Kit – Complete Water Control
The Cykemo kit bundles a W10327249 water inlet valve and a W10195039 float switch, giving you a comprehensive solution for water control issues in Whirlpool, KitchenAid, Kenmore, and Maytag dishwashers. The inlet valve regulates water flow into the machine, while the float switch monitors the level and shuts off the valve if it gets too high. Together, they ensure your dishwasher fills correctly and doesn’t overflow.
Both parts are made from high-quality, heat-resistant, and corrosion-resistant materials, which is crucial for long-term reliability in a hot, wet environment. The kit replaces multiple part numbers including W10195047, AP6019618, PS11752927, and others, so it’s likely to fit your model. You get the inlet valve and the float switch in one package, saving you from ordering separate parts. If you’re dealing with both water fill and level issues, this combo is a smart buy.

D.I.Accessa W10195039 2-Pack – Double Protection
Brand: D.I.Accessa
A cost-effective 2-pack for those needing spares or dual repairs.
If you own multiple Whirlpool-family dishwashers or just want a spare on hand, the D.I.Accessa W10195039 2-pack is a practical option. This package includes two identical float switches, each serving as a replacement for AP6016738, PS11750031, W10734532, and WPW10195039. It’s compatible with Whirlpool, KitchenAid, Maytag, Amana, Jenn-Air, and Inglis models, so you’re covered across several brands.
The switch operates the same way as the single-pack version: it closes the water inlet valve if the water level exceeds the limit before the fill cycle ends. That means you get the same reliable overflow protection, but with the convenience of having a backup. Whether you’re repairing two dishwashers or just want to avoid a future shipping wait, this 2-pack offers good value. The switches are easy to install, and the extra unit can sit in your toolbox until needed.

The Lumiparts kit includes both the water level float (W10195036) and the float switch (W10195039), so you get the complete water level control system in one order. The float monitors the water level with a responsive design, addressing issues like abnormal water intake, overflowing, low water, loud noise, and poor cleaning. The switch then works to shut off the inlet valve if levels get too high, ensuring safe operation.
This combo is particularly useful if you’re not sure whether the float or the switch is the problem—replacing both at once saves time and avoids a second repair. The parts are made from corrosion-resistant, high-temperature-resistant materials, so they’re built to last.

Buyer’s Guide: What to Consider
Choosing the right float switch involves more than just picking a part number. Consider compatibility, whether you want OEM or aftermarket, and if you need a kit. Here are key factors to guide your decision.
- Compatibility: Always check that the float switch matches your dishwasher's brand and model. Look for part numbers like W10195039 or WD21X10519 that are known to fit your machine. Cross-reference with your owner's manual or the old part to avoid mismatches.
- OEM vs Aftermarket: OEM parts, like the Whirlpool W11545764, are made by the original manufacturer and offer a perfect fit and warranty. Aftermarket parts, like NOVINO's, are cheaper but may vary in quality. Decide based on your budget and how long you plan to keep the dishwasher.
- Kit vs Single Part: Some kits include both the float and switch, or even a water inlet valve, which can be handy if you're unsure which component is faulty. Single parts are cheaper if you know exactly what's broken. Consider the potential for future repairs when choosing.
- Installation Difficulty: Most float switches are DIY-friendly, requiring basic tools like screwdrivers. Some kits, like the Parzuozenney, come with clear instructions or video guides. If you're not handy, factor in the cost of professional installation, which might make a pricier OEM part less appealing.
- Durability and Materials: Look for switches made with corrosion-resistant and heat-resistant materials, as they'll last longer in the humid dishwasher environment. ABS plastic housings and corrosion-resistant terminals, as seen in some aftermarket options, are good indicators of longevity.
Conclusion
Replacing a faulty dishwasher float switch is a straightforward repair that can save you from costly water damage. Whether you opt for a budget-friendly aftermarket part or a genuine OEM switch, the key is to ensure compatibility with your specific model. For most Whirlpool-family dishwashers, the D.I.Accessa single or 2-pack offers reliable performance, while GE owners might prefer the Parzuozenney or NOVINO options.
If you value authenticity and warranty, the Whirlpool OEM switch is a solid investment. For a comprehensive fix, consider kits like the Cykemo or Lumiparts that include multiple components. Whichever you choose, always verify your model number before purchasing to ensure a perfect fit.
