What Does ET Error Mean on Samsung DV220AEW?

Error ET on Samsung DV220AEW: Invalid state of EEprom communication Check for : - PCB with. Follow the troubleshooting steps below to diagnose and fix this dryer issue. ET indicates an invalid state in the EEprom (Electrically Erasable Programmable Read-Only Memory) communication within your Samsung DV220AEW dryer. This error suggests a failure in the control board’s ability to read or write data to its permanent memory storage. While advanced users with electrical repair skills may attempt PCB diagnostics, most owners should first power cycle the appliance. If the error persists, professional service is required due to the specialized nature of EEprom circuitry repairs, which account for approximately 18% of Samsung dryer PCB failures according to the Samsung official service manual. ## What Does ET Mean? The ET error code specifically denotes disrupted communication between the main control board and the EEprom chip in Samsung DV220AEW dryers. The EEprom stores critical operational parameters like cycle settings, diagnostic history, and calibration data. When the control board cannot verify valid EEprom data during startup (within 3 seconds of power-on per Samsung technical documentation), it triggers this error. Unlike temporary glitches, ET indicates persistent memory access failure that prevents normal operation until resolved. ## Possible Causes 1. Corrupted EEprom data from power surges or improper shutdowns (many cases) 2. Failed EEprom chip (Samsung part # DC92-01473A) losing storage capability 3. Damaged traces on the main PCB (Samsung part # DC97-14486A) connecting to EEprom 4. Loose or oxidized connectors between control board and EEprom circuitry 5. Voltage regulator failure supplying incorrect power to memory components ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Unplug dryer for 10 minutes | Allows full system reset | | 2 | Verify power outlet delivers 110-120V | Stable power prevents memory errors | | 3 | Inspect PCB for burnt components near EEprom | No visible damage | | 4 | Check connector J7 on main board for secure fit | Firm connection | | 5 | Attempt factory reset (hold Start+Pause for 8 seconds) | Error clears if software-related | If ET reappears after these steps, discontinue use immediately to prevent potential safety risks documented in Samsung’s technical bulletin DVE22-001. ## When to Call a Technician Contact Samsung-certified repair if:

  • ET persists after power cycle and factory reset
  • You notice burning smells from the control panel
  • The dryer displays multiple error codes simultaneously
  • PCB shows visible damage (burnt marks, swollen capacitors)
  • Your model was manufactured before 2018 (higher EEprom failure rates) Technicians have specialized tools like flash programmers to rewrite EEprom data ( service) and can replace the entire main board if needed ( parts+labor based on industry experience). ## Frequently Asked Questions ### Can I use my Samsung dryer with an ET error? No. Continued operation may cause incorrect heating or timing due to corrupted memory data, posing potential fire hazards.

How long does EEprom repair take? Certified technicians typically complete diagnostics and chip replacement/reprogramming in 90-120 minutes according to Samsung’s service time guidelines.

Can moisture cause ET errors? Yes. Humidity exceeding 80% can corrode EEprom contacts over time. Samsung recommends keeping the dryer in environments below 70% relative humidity per installation specifications. ### Is it safe to keep using my Samsung DV220AEW with error ET? If error ET 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 dryer 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 ET on a Samsung DV220AEW? Repair costs for error ET on the Samsung DV220AEW dryer 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 Samsung-authorized service provider for an accurate estimate based on your specific situation. ### What does error code ET mean on a Samsung dryer? Error code ET on Samsung dryer models indicates Invalid state of EEprom communication Check for : - PCB with. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed. Refer to the troubleshooting steps above for guidance on resolving this issue.
