So, your dishwasher isn’t behaving itself, huh? Don’t worry, you’re not alone. One common culprit behind dishwasher woes is a faulty float switch. This little guy might seem insignificant, but it’s actually a big deal when it comes to regulating water levels inside your dishwasher. If it’s acting up, you might notice your dishwasher overfilling, underfilling, or just not filling at all. But fear not! In this blog post, Maricopa Repair walk through the process of replacing that pesky float switch, so you can get your dishes sparkling clean again in no time. Let’s dive in!
Understanding the Float Switch
Before diving into the replacement process, it’s essential to understand the role of the float switch within the dishwasher. The float switch is a mechanism designed to monitor the water level inside the dishwasher’s tub. It consists of a float, typically made of plastic or foam, which rises and falls with the water level. As the water level increases, the float rises, activating the switch to stop the flow of water. Conversely, when the water level decreases, the float descends, allowing the switch to signal the dishwasher to fill with water again. This cycle repeats throughout the wash and rinse cycles, ensuring optimal water levels for effective cleaning.
The float switch in a dishwasher plays a crucial role in regulating water levels during operation. It consists of a float that rises and falls with the water level, triggering the switch to stop or start the flow of water accordingly. Understanding how the float switch functions is essential for troubleshooting and repair.

Identifying Signs of a Faulty Float Switch
Before proceeding with the replacement, it’s crucial to diagnose whether the float switch is indeed the culprit behind the dishwasher’s malfunction. Several indicators suggest a faulty float switch:
- Overfilling or Underfilling: If the dishwasher consistently fills with too much water or not enough water during the wash cycle, it could signal a malfunctioning float switch.
- No Water Filling: If the dishwasher fails to fill with water altogether, the float switch may be stuck in the raised position, signaling to the appliance that the tub is already full.
- Continuous Filling or Draining: A malfunctioning float switch can cause the dishwasher to continuously fill or drain water, even when it’s not in use, leading to potential flooding or drainage issues.
- Visible Damage: Inspect the float switch for any visible signs of damage, such as cracks, breaks, or debris accumulation, which may hinder its proper functioning.
Gathering Necessary Tools and Materials
Before starting the replacement process, gather all the required tools and materials to ensure a smooth and efficient repair. Here’s a list of commonly needed items:
