Common Dishwasher Problems We Solve

Our extensive experience with dishwasher service in Reading, MA allows us to quickly diagnose and fix the full range of operational failures. We understand that every issue, from a minor noise to a major leak, is frustrating. Our expertise ensures a prompt resolution to the most common, and most challenging, dishwasher malfunctions.

Dishwasher Not Draining

One of the most common and disruptive problems is a dishwasher not draining, leaving standing, dirty water in the basin after a cycle finishes. This issue can be caused by several factors, ranging from simple clogs to complex component failures. Often, the issue is a clogged air gap or a blockage in the drain hose itself, which prevents water from successfully exiting the unit and flowing into the disposal or drain line. However, a more serious cause could be a malfunctioning drain pump, which is the mechanical part responsible for forcing the water out. Alternatively, the electronic control board may not be correctly sending the signal to activate the pump. Our technicians expertly check the drain pump, the impeller, and all associated plumbing lines to pinpoint the exact obstruction or component failure and deliver a reliable fix for the dishwasher not draining problem.

Dishes Are Still Dirty or Wet

The primary purpose of your appliance is to deliver clean, dry dishes. When dishes are still dirty or wet, it indicates an operational failure. Dirty dishes can result from a clogged spray arm that prevents water circulation, a faulty wash pump that is not achieving sufficient pressure, or a malfunctioning detergent dispenser that is failing to release the cleaning agent at the correct time. If dishes are still wet after the drying cycle, the heating element may be failing, or the vent system responsible for moving moist air out of the unit may be blocked. We meticulously check all spray arms for blockage, confirm the wash pump pressure, and verify the heating element and thermostat function to ensure your unit is operating at peak efficiency, eliminating the need for pre rinsing and towel drying.

Dishwasher is Leaking Water

A dishwasher leaking water is a serious problem that can lead to cabinet or flooring damage if not addressed quickly. Leaks can originate from various points. Simple leaks might be caused by a dried out or improperly seated door gasket that allows water to escape when the unit is running. More complicated leaks often originate from a damaged tub or a faulty component within the unit’s plumbing, such as a cracked hose, a failed pump seal, or a faulty water inlet valve that allows excessive water into the tub. To correctly fix a leak, our dishwasher repair technician must trace the exact source, which often requires opening the unit and inspecting internal components. We use precise diagnostic methods to ensure we resolve the leak at its source, protecting your kitchen from further water damage.

Dishwasher Won’t Start

A dishwasher won’t start problem can be particularly confusing for homeowners because the cause could be electrical, mechanical, or digital. The simplest cause might be a tripped circuit breaker or a faulty power supply. However, the issue is often related to a safety mechanism, such as a broken door latch or switch, preventing the machine from operating until the door is properly secured. The problem could also lie in the electronic control board or timer, which is the brain of the unit. These digital components manage the entire cycle and may fail to send the initial start command. Our diagnostic process carefully isolates the source of the failure, checking the electrical supply, testing the door latch mechanism, and assessing the control board integrity to provide a fast solution to a common frustration.

Dishwasher is Making Loud or Unusual Noises

While all dishwashers produce some operational noise, a sudden change to a loud or unusual noise often signals a mechanical problem. A grinding or screeching noise typically indicates an issue with the wash pump motor, perhaps due to a failing bearing or an object that has found its way into the pump assembly. A clanking noise is usually simpler, often caused by a loose spray arm hitting a dish or a utensil that has fallen into the tub. A persistent humming noise without any wash action suggests a blockage in the drain pump or wash pump impeller. Addressing a noisy dishwasher fix requires the technician to access the pump assemblies beneath the unit, which is a complicated process that should always be performed by a professional dishwasher technician to prevent further damage to these critical internal parts.

Dishwasher is Displaying an Error Code

Modern dishwashers use electronic error codes to communicate problems, but interpreting these codes can be challenging without proper knowledge. These codes often point to specific component failures, such as a water supply issue, a heating element malfunction, or a communication breakdown between sensors. While an error code provides a starting point, it rarely tells the whole story; for example, a code indicating low water may be caused by a faulty inlet valve, a broken float switch, or a simple plumbing restriction. Our dishwasher repair experts are trained to translate these codes into actionable repairs, diagnosing the underlying cause instead of just resetting the code, ensuring a lasting resolution to the problem.

Dishwasher Door Won’t Latch

The dishwasher door won’t latch is a common safety related issue. Dishwashers are designed with interlocking mechanisms that prevent operation unless the door is securely closed and latched, which is a vital safety feature to prevent leaks and sprays. The latch mechanism itself is a common point of failure, often breaking from repeated use or becoming misaligned. The plastic or metal strike plate on the door or tub may be bent, preventing the latch from engaging. The electronic door switch, which tells the control board that the door is secured, may also fail, even if the latch appears to catch. We carefully inspect and replace the latch assembly and switch, ensuring a secure seal before the unit begins its next cycle, allowing for safe and leak free operation.
