Maytag Washing Machine Displays an Error After Draining Water — Possible Pressure Sensor or Drain Pump Issues

A Maytag washing machine should transition smoothly from draining water to the next stage of the cycle. If the machine finishes draining but immediately displays an error code, it is usually detecting a problem that prevents it from continuing safely. While the exact code varies by model, the underlying issue often involves the pressure sensor, drain pump, or another component responsible for monitoring water levels and drainage.

Ignoring repeated error messages can lead to incomplete wash cycles, poor cleaning results, and more expensive repairs. Understanding the most common causes can help you determine when professional service is needed.

How the Washer Knows the Drum Is Empty

Before advancing to the rinse or spin cycle, the control system must confirm that the wash water has been completely removed.

The drain pump forces water out through the drain hose, while the pressure sensor monitors the water level inside the tub. Once the control board receives confirmation that the drum is empty, the cycle continues.

If the control board does not receive the expected signal, it may stop the program and display an error code.

Faulty Pressure Sensor

A defective pressure sensor is one of the most common reasons a Maytag washer displays an error after draining.

The pressure sensor measures the water level by monitoring air pressure inside a connected hose. If the sensor provides inaccurate readings or fails to respond, the control board may incorrectly assume that water is still inside the drum, even after draining has finished.

Common signs of pressure sensor problems include:

  • Error codes after draining.
  • The washer refuses to enter the spin cycle.
  • Repeated draining attempts.
  • Incorrect water levels during washing.
  • Cycles that stop unexpectedly.

Pressure sensors may fail because of age, moisture, electrical faults, or internal wear.

Drain Pump Problems

The drain pump is responsible for removing water from the washer.

If the pump becomes partially clogged, damaged, or electrically defective, it may not remove all of the water before the control system checks the water level. Even a small amount of remaining water can trigger an error.

Pump problems are often accompanied by slow draining, humming noises, or standing water inside the drum.

Blocked Drain Hose

A restricted drain hose can create symptoms similar to a failing pump.

Lint, detergent residue, or small objects may reduce water flow enough to delay complete drainage. The pressure sensor may continue detecting water, causing the control board to display an error instead of advancing the cycle.

Inspecting the drain hose is an important part of any diagnosis.

Air Hose Issues

The pressure sensor relies on a small air hose connected to the outer tub.

If this hose becomes blocked, kinked, disconnected, or develops a leak, the pressure readings may become inaccurate. As a result, the control board may receive incorrect information about the actual water level.

Replacing the sensor without checking the hose may not solve the problem.

Electronic Control Board Failure

Although less common, the electronic control board itself can also trigger errors after draining.

If damaged by electrical surges, moisture, or failing internal components, the board may misinterpret sensor readings or fail to recognize that draining has completed.

Because control board failures often resemble sensor problems, proper testing is essential before replacing expensive electronic parts.

Wiring and Electrical Connections

Loose wiring between the drain pump, pressure sensor, and control board can interrupt communication during the cycle.

Years of vibration may loosen connectors or damage wiring insulation, creating intermittent faults that are difficult to identify without diagnostic equipment.

Technicians routinely inspect electrical connections before replacing major components.

Why Early Repairs Matter

Repeatedly restarting the washer after an error code appears rarely solves the underlying problem.

Incomplete drainage places additional stress on the drain pump, while repeated cycle interruptions increase wear on electronic components. Prompt repairs often prevent more extensive and costly damage.

Early diagnosis also helps maintain efficient washing performance and reduces water and energy waste.

Professional Diagnosis

Because pressure sensor failures, pump problems, clogged hoses, and control board faults can all produce similar error messages, replacing parts without testing may result in unnecessary expenses.

Professional technicians use specialized diagnostic tools to determine exactly which component has failed before performing repairs.

If your Maytag washing machine displays an error immediately after draining water, don’t ignore the warning. A faulty pressure sensor, drain pump, blocked hose, or control board issue can prevent the washer from completing the cycle and may lead to additional damage over time.
