ariston boiler sp3 error

What is the sp3 Ariston error fault affecting your boiler?

If you have an Ariston boiler, you've probably heard about this error code. If you're here, it's likely because you're encountering it right now and need a solution. You're in the right place!

The first thing we need to do before tackling the problem and finding a solution is to confirm if you truly have this Ariston boiler error code on your Ariston brand boiler. It happens that many users confuse the error code "SP3" with "5P3". This is because on the boiler's LED screen, the number "5" looks a lot like the letter "S".

This error code arises because the boiler has attempted to ignite at least 3 times and hasn't succeeded in any of them. It's a problem that could be related to the flame ignition or with the gas that fuels the flame.

Among the possible causes that can trigger this error code on your boiler, the following are some. Don't worry, we'll provide a brief explanation for each:

  • Gas supply failure: If the gas supply to your boiler is cut off for some reason, the error code will appear because the boiler hasn't been able to ignite. You might have a leak, so be cautious as it could be dangerous.
  • Very low water pressure: If the water supply to the boiler is insufficient for its operation, it won't work properly. A water supply issue can also be a reason for this error code to appear on your boiler.
  • Defective sensor or lack of maintenance: There's a sensor in the boiler that detects whether the flame is on or off. If this sensor malfunctions, the boiler will think it doesn't have a flame to fuel it and thus, it will shut off by itself and try to restart several times until it displays the error code SP3 or 5P3.

How to fix the sp3 error of the Ariston boiler?

Fortunately, this kind of error has a swift and effective solution. We'll provide a series of steps you can follow to try to fix the problem on your own. However, as the boiler issue relates to a flame or gas supply malfunctions, we recommend entrusting the problem to an expert:

  1. Restart your Ariston boiler: When we restart the boiler, the sensors reset and recalibrate. Perhaps by initiating a restart, we can clear the error code. To do this, you'll need to turn off your boiler and disconnect it from the power socket, wait a few minutes and plug it back in. Check to see if the error code has disappeared upon turning it on.
  2. Check the gas supply: Ensure there's no leak in the gas supply leading to your boiler, or check outright if the service hasn't been entirely suspended. If it's cut off, inspect the valves supplying gas to your home and verify that everything is in order.
  3. Check the water pressure: Insufficient water pressure will cause your boiler to malfunction and shut off. You'll need to examine the water supply passing through the boiler; turn up the faucet slightly if needed.
  4. Inspect the pressure gauge: This device measures the pressure inside the boiler. It shouldn't be below 1 bar and should not exceed 1.5 bar. If it's below 1 bar, slightly open the valve and check everything again. If it exceeds 1.5 bar, you'll need to partially close the valve until it stabilizes.
  5. Maintenance of the sensors: Consider maintaining the sensors of your boiler. Using some electronic spray cleaner might suffice. However, we recommend a more thorough maintenance of your entire boiler to ensure its optimal performance and extend its lifespan.
  6. Double-check everything: If you've done all we've suggested and still haven't resolved the error code, try checking everything once more. Ensure you follow all the steps to the letter.
  7. Seek assistance from Ariston's technical service: Sometimes, it's best to leave things to a professional. Remember, this error code may relate to a gas leak, so we advise letting an expert handle it. We're confident that Ariston's technical support can help you address this issue quickly and, most importantly, safely.

In conclusion, we can summarize the following steps to resolve the SP3 error code on the Ariston boiler:

  • Restart the boiler
  • Check the gas supply
  • Check the water supply
  • Inspect the pressure gauge
  • Maintain the sensors
  • Ensure everything is in order
  • Seek technical support

We hope to have helped you solve your problem. Ariston boilers are top-notch in terms of quality and performance, but sometimes they require proper maintenance just like any other appliance.
