Baxi fault code E.02.13 means total stoppage of the boiler, with the antifreeze function not active. Baxi lists this wording for applicable Combi 2 and System 2 boilers.
The boiler has stopped rather than continuing normal heating or hot-water operation. Because the appliance’s own antifreeze function is not active, you should not rely on it to protect the boiler during cold weather. The code does not confirm why the stoppage occurred, so keep the casing closed and arrange repair if it does not clear in accordance with the exact user guide.
What does Baxi E.02.13 mean?
“Total stoppage” means the boiler controls have halted operation. Baxi adds that the antifreeze function is not active under this condition. That function is designed around the appliance itself; it should never be described as guaranteed protection for every pipe, radiator or part of the property.
E.02.13 reports an operating state, not a single failed component. An engineer must use the correct model information and fault history to establish what has caused the boiler to stop.
Which Baxi boilers use E.02.13?
Baxi places E.02.13 in its current Combi & System 2 group. The listed ranges include the Baxi 200, 400, 600 and 800 Combi 2, the Assure 500 Combi 2, and the Baxi 600, 800 and Assure 500 System 2 boilers.
Other Baxi models can use different displays and frost-protection arrangements. Check the model name visible on the appliance and use only the matching user guide. Do not assume instructions for one Baxi range apply to another.
What does “antifreeze function not active” mean?
On the applicable boiler, the built-in protection routine is not operating while E.02.13 is present. This matters most during freezing weather, but it does not mean pipes have already frozen or that damage is certain.
It also does not mean the boiler should be forced back into operation. Repeated resets or changes to internal settings can interfere with protective controls and must be avoided.
What can you safely check?
Without opening the boiler, you can:
- Write down E.02.13 exactly as displayed.
- Confirm the exact model name from the outside of the appliance.
- Note whether heating, hot water or both have stopped.
- Check whether the property has electrical power and whether there is a known outage.
- Look at the normal pressure display or external gauge and record the reading.
- Check for visible water, staining or frost on accessible external pipework without dismantling anything.
- Record the outdoor temperature and when the fault first appeared.
Do not remove covers, use installer menus, alter sensors or wiring, or attempt internal pump or valve work. Do not use a naked flame, blowtorch or boiling water on frozen pipework.
Should you reset E.02.13?
Consult the user guide for your exact Baxi model. If it permits a homeowner reset, one careful attempt is reasonable when there is no smell of gas, carbon-monoxide warning, visible leak near electrics or sign of damage.
If the code remains or returns, stop resetting and arrange a repair. A total stoppage with inactive frost protection needs attention rather than repeated attempts to keep the appliance running.
What should you do in freezing weather?
Act early to reduce the risk to the property while waiting for repair. Keep internal doors open where appropriate so warmer air can circulate, close curtains after dark and follow your insurer’s or landlord’s cold-weather guidance. If you know how to isolate the water supply safely, make sure the stop tap remains accessible in case a pipe bursts.
If you use portable electric heaters, follow the manufacturer’s instructions, keep them well clear of curtains, bedding and furniture, plug them directly into a suitable wall socket, and never leave them unattended. Do not use ovens, barbecues or outdoor heaters to warm the home.
If you are a tenant, notify the landlord or managing agent promptly. Vulnerable occupants should seek additional help if the home cannot be kept safely warm.
Does E.02.13 mean the condensate pipe is frozen?
No. A frozen external condensate pipe can stop a boiler in cold weather, but E.02.13 does not specifically identify that cause. Do not assume a visible external pipe is responsible or apply a generic thawing procedure unless the exact user guide confirms it.
If accessible pipework is visibly frozen, follow current manufacturer guidance only. Never remove boiler panels or interfere with the flue.
What will an engineer do?
A Gas Safe registered engineer will confirm the exact model, examine the fault history and use Baxi’s service information to identify why the boiler has entered total stoppage. The display alone does not say which component or control condition needs correction.
When booking, provide the full code, model name, visible pressure, outdoor conditions and whether the property has recently had a power interruption. Our boiler help guides explain other manufacturer messages, while all internal work should remain with the engineer.

Quick answers about Baxi E.02.13
What does E.02.13 mean on a Baxi boiler?
It means total stoppage of the boiler with its antifreeze function not active.
Is my whole home protected from frost by the boiler?
No. The boiler’s antifreeze function is appliance-specific and should not be treated as guaranteed protection for the entire property or heating system.
Can I reset Baxi E.02.13?
Follow the exact model’s user guide. If it permits a reset, try it once. A code that remains or returns needs professional repair.
Does E.02.13 prove the condensate pipe is frozen?
No. The code describes total stoppage with frost protection inactive; it does not identify a frozen condensate pipe as the cause.
