If a SARF gas meter displays ERR-15, ERR-16, ERR-17, ERR-28, ERR-31 or ERR-32, it does not always mean the meter has failed. Some codes describe the shut-off valve status, while others indicate battery, reverse-flow or meter faults. This guide explains what the main codes mean and what users in Uzbekistan should do.
SARF gas meter error codes
| Code | Meaning | Recommended action |
|---|---|---|
| ERR-15 | Shut-off valve is closed | Check whether the meter has been registered and commissioned. If the valve remains closed, contact SARF service or Hududgaz. |
| ERR-16 | Valve closed after a tightness check | Switch off all gas appliances and close their valves. If the error returns, contact a technician. |
| ERR-17 | Low or depleted battery | Contact service for battery inspection and replacement. Do not open a sealed meter yourself. |
| ERR-28 | The shut-off valve may be opened | Make sure all gas appliances are off and there is no smell of gas, then use the meter's normal valve-opening procedure. |
| ERR-31 | Reverse gas flow detected | Have the installation direction and network pressure checked if the code persists. |
| ERR-32 | Meter malfunction | The meter requires diagnostics. Do not dismantle or repair it yourself. |
ERR-15 — shut-off valve closed
ERR-15 means that the built-in shut-off valve is closed.
This does not necessarily indicate a broken meter. On a newly installed unit, the valve may remain closed until registration and commissioning have been completed.
📌 If the meter was previously operating normally and ERR-15 appears unexpectedly, contact SARF service or the gas supplier to determine why the valve was closed.
ERR-16 — valve closed after a tightness check
ERR-16 may appear when the meter does not confirm a safe condition after the valve-opening or tightness-check procedure and closes the valve again.
Before trying again:
- switch off the cooker, boiler and other gas appliances;
- close their gas valves;
- make sure there is no smell of gas;
- only then use the standard valve-opening procedure.
If ERR-16 keeps returning, stop trying to reset it and contact a technician.
ERR-17 — battery depleted
ERR-17 is commonly associated with a depleted internal power source.
The battery powers the meter electronics, display, modem and valve system.
⚠️ Do not open a sealed meter to replace the battery yourself. Contact SARF service at +998 95 500-88-88.
ERR-28 — valve may be opened
ERR-28 is not necessarily a fault. It indicates that the shut-off valve is in a state in which it may be opened.
Before opening it:
- switch off all gas appliances;
- close their valves;
- make sure there is no smell of gas;
- use the meter's normal button-operated valve-opening procedure.
ERR-31 — reverse gas flow
ERR-31 means the meter detected gas flowing in the reverse direction.
Possible causes include the installation direction, fluctuations in gas-network pressure or a temporary reverse flow when gas supply is interrupted.
If the message remains on the display, the installation and gas-flow direction should be checked by a qualified specialist.
ERR-32 — meter malfunction
ERR-32 indicates a meter fault requiring diagnostics.
Do not:
- open the meter housing;
- break or remove seals;
- repair the shut-off valve yourself;
- apply an external power supply;
- remove or reposition the meter.

❓ Frequently Asked Questions About SARF Gas Meter Errors
Click or tap a question to reveal the answer ↓
What should I do first when a SARF error appears?
First check whether you smell gas. If you do, stop any restart attempt, leave the premises and call 104 from a safe location. Do not use flames or operate electrical switches. If there is no gas smell, photograph the display and identify the code using the manual for your exact meter version.
What does ERR-15 tell me?
In the configuration described in this article, ERR-15 indicates that the shut-off valve is closed. On a newly installed meter, check that registration and commissioning have been completed. If the message appears unexpectedly on a working meter, ask the gas supplier or SARF service to establish why the valve closed.
What should I check when ERR-16 appears?
Switch off all gas appliances and close their supply taps. The article associates ERR-16 with the valve closing after a tightness check. If the code returns, stop reopening attempts and arrange a specialist’s inspection before resuming use.
How should I resolve ERR-17?
Arrange a battery inspection through an authorised service technician. The article associates ERR-17 with a low or depleted internal power source. Keep the meter casing and seals intact; the technician should confirm the fault and perform any necessary battery replacement.
What does ERR-28 mean?
For the configuration described, ERR-28 relates to permission or confirmation to open the valve. It does not by itself establish a meter failure. Use only the normal opening procedure specified for your exact model, after the interruption’s cause has been resolved, with no gas smell and all gas appliances off and their supply taps closed.
What action is needed for ERR-31?
The article identifies ERR-31 as reverse gas flow detected by the meter. Record the message and arrange for a qualified specialist to check the installation direction and supply conditions if it persists. Leave the meter and its connections in place.
How can diagnostics help with ERR-32?
Diagnostics establish the cause of the reported meter malfunction and the appropriate remedy. ERR-32 alone is not enough to decide whether repair or replacement is needed. Keep the casing, seals and valve intact and contact the service team.
What information should I prepare for the service team?
Prepare your address, customer account number, meter model, serial number and a clear display photograph. Record when the error appeared and which actions you took. Include a payment receipt if the interruption followed an account-balance issue.
Who should I contact for help?
The article lists SARF / iMeter service at +998 95 500-88-88 and Hududgazta’minot at 1104. For a gas smell or suspected leak, leave the premises and call 104 from a safe location.
