Error Code E31 on TCL TWF80-B102WH Washer | Causes & Fix

Error E31 on TCL : Water inlet fault — water not reaching required level. Follow the troubleshooting steps below to diagnose and fix this washer issue. ## What Error Code E31 Means on a TCL TWF80-B102WH Error E31 on the TCL TWF80-B102WH washer indicates the machine has not reached the required water level within the fill timeout. The pressure switch (or pressure sensor on electronic models) must detect the minimum water level within approximately 5 minutes. If it does not, E31 is raised and the inlet valve closes. The most common cause is a closed or partially closed water tap, a kinked inlet hose, or a blocked inlet filter mesh. When E31 appears, the TCL washer pauses normal operation to protect internal components from potential damage. Not every E31 fault requires a professional engineer — many are resolved through careful inspection and routine maintenance. Work through each diagnostic step below in sequence, starting with the simplest check, to identify the root cause efficiently before considering part replacement or arranging a service call. ## Symptoms - E31 on display

  • No water sounds during fill phase
  • Drum empty after fill stage ## Common Causes - Water inlet fault — water not reaching required level ## Tools You May Need - digital multimeter
  • long-nose pliers
  • bucket ## Step-by-Step Repair Guide | Step | Action | Result | |------|--------|--------| | 1 | Check the water tap is fully open and the inlet hose is not kinked. | Water supply confirmed — continue to step 2 if the issue persists. | | 2 | Unscrew the inlet hose from the machine and clean the filter mesh. | Mesh cleaned — continue to step 3 if the issue persists. | | 3 | Reconnect hose, restore power, and start a rinse cycle to test fill. | Machine fills or fault persists — continue to step 4 if the issue persists. | | 4 | If fault persists, unplug and test the inlet valve solenoid: ~4–8 kΩ is normal; OL means failed valve. | Solenoid measured — continue to step 5 if the issue persists. | | 5 | Replace the inlet valve if solenoid tests open-circuit. | Valve replaced — if the fault remains, contact a qualified technician. | ## Safety Precautions Turn off the water supply tap before disconnecting the inlet hose to avoid flooding. ## Estimated Repair Time and Difficulty Most washer error code E31 faults can be assessed and addressed in 30–90 minutes using the steps above. The diagnostic process requires only basic tools: a multimeter and standard screwdrivers cover the majority of checks described here. If a replacement part is required, allow 1–5 working days for delivery. A trained technician with access to the correct diagnostic equipment will typically resolve this type of fault within a single service visit. ## When to Call a Technician Contact a TCL authorised service technician if: the fault persists after following all the steps above; if PCB-level or refrigerant-circuit work is required; or if you are not comfortable working with electrical or mechanical components. When calling, have the full model number, the error code displayed, and a brief description of any sounds or symptoms you noticed before the fault appeared — this helps the technician prepare the correct parts and tools. ## Frequently Asked Questions Q: Can low water pressure cause E31? Yes. TCL recommends minimum static pressure of 0.05 MPa. Intermittent E31 can indicate borderline pressure — check with your water supplier. Q: Is E31 the same as an overflow error? No — E31 is an under-fill fault. E81 is the TCL code for overflow. Q: How do I access the inlet valve on a TCL washer? Remove the top panel (two or three screws at the rear) — the valve is at the top-right corner. ### Is it safe to keep using my TCL with error E31? If error E31 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the washer with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error E31 on a TCL ? Repair costs for error E31 on the TCL washer depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a TCL-authorized service provider for an accurate estimate based on your specific situation. ### What does error code E31 mean on a TCL washer?
