When a washing machine error appears in a Tokyo apartment, the cause is often related to one of the following: “drainage,” “water intake,” “water level detection,” or “motor protection.” Here, we’ll walk through—step by step—the quickest route to safely narrow down the issue, from how to read the error code to the appropriate troubleshooting steps.

First, check these 3 (to avoid power outages and water leaks)

  1. Turn off the power. Before starting any work, be sure to unplug the power cord or switch off the breaker at the electrical panel.
  2. Visually inspect the water supply source and drainage route. We check for any hose kinks, loose connections, or clogged drains.
  3. Write down the error code. Record the displayed alphanumeric characters (e.g., Exx) as-is, and if possible, also note the device model name.

Typical symptoms with a high frequency of occurrence in your home in Tokyo

The drainage stops and the spin is weak

In apartment buildings, drainage routes are shared and tend to clog more easily. First, check the drainage filter, any clogs in the drain hose, and dirt buildup in the circulation line.

Do not supply water, water supply error

Water valve opening and closing, blockages inside the hose, and poor sealing during installation are often the causes. On days when water pressure is low, “checking” is the faster route than “waiting.”

Water level is abnormal, stop

Typical issues around the water level sensor include dirt buildup, a clogged pressure tube, and an imbalance inside the drum. For safety, do not force anything into the interior.

Abnormal vibration, rotation stopped

Horizontal positioning check, the presence or absence of transport bolts, and the tilt of the installation floor all have an impact. First, we observe the “conditions that produce noise and vibration,” and then narrow down the cause.

Solve step by step: troubleshooting flow by error code

This page is a guide to standardize how error codes are handled. Check from the item closest to the code you see, and if it doesn’t match, move on to the next item.

A. Crush the drainage side first

  • Open the drain filter to remove debris and dirt
  • Inspect within the range where you can remove the drain hose, and check for clogs
  • Check the water flow in the drain opening

If drainage does not improve, proceed to the next step: water supply and water level detection.

B. Check water supply and water level detection

  • Water hose routing and sealing of connection points
  • Inspect the area around the water level sensor for dirt (avoid unnecessary disassembly)
  • If it stops after the water is turned on, first check whether “water is entering.”

Here are the cases where improvement often involves reviewing cleaning and connections.

Signs that may indicate a need for replacement

If the error keeps repeating under the same conditions even though it doesn't return after cleaning, it may be due to component wear. Watch out for the following signs:

  • Even if you change the filters and hoses, it stops at the same time
  • After providing water, it suddenly transitions to an error after a short while.
  • The water is flowing even though the drainage is weak (meaning the blockage is located elsewhere)

Next steps (actions you can try right away)

Error codes: meaning and solutions vary in details by model. To move through the quickest path based on your device, gather the information starting from the displayed code.

Frequently Asked Questions (short and reliable)

What should I do if multiple codes are displayed?

Please record the code that was first generated as the priority. The next code is often shown as the “result.”

Would it be faster to check the video?

Yes. It makes the mounting direction, the cleaning area, and which parts you can touch clear, so mistakes are less likely.

Could it be fixed without needing to disassemble?

It isn’t always the case. First, check the filter, the hose, and the connection—many issues can be resolved this way.

Please work safely and move forward without overexerting yourself. Comparing your progress with the following checklist will help you reach the root cause more quickly.
