How to Reset Ideal Logic Combi 30 Boiler – Step-by-Step Expert Guide

Understanding Boiler Lockout on Ideal Logic Combi 30

The Ideal Logic Combi 30 boiler is designed with built-in safety controls that continuously monitor pressure, gas flow, ignition, and temperature. When a fault is detected, the system automatically shuts down and enters boiler lockout mode.

A boiler lockout is not a failure—it is a safety feature. Lockouts prevent unsafe operation, protect internal components, and reduce the risk of gas or heating system damage. Some lockout causes are simple and homeowner-friendly, while others require professional diagnosis.

Understanding why a boiler lockout occurs helps prevent repeated shutdowns and costly repairs.

Common Reasons Ideal Logic Combi 30 Needs a Reset

1. Low Boiler Pressure
Low pressure is one of the most common causes of boiler lockout. It often happens after bleeding radiators, small system leaks, or gradual pressure loss over time.

• Ideal pressure (cold system): 1.0–1.5 bar
• Pressure below this range can stop ignition
• Always check the gauge before attempting an Ideal Logic boiler reset

If pressure is low, topping up via the filling loop may restore normal operation.

2. Gas Supply Issues
A continuous gas supply is essential for boiler operation. The boiler may lock out if:

• A prepayment gas meter has run out
• There is temporary gas disruption
• Local maintenance work affects supply

Without gas, ignition fails and the boiler enters lockout mode.

3. Ignition or Flame Failure
Ignition faults occur when the boiler cannot detect or sustain a flame. Common causes include:

• Fluctuating gas pressure
• Worn ignition electrodes
• Faulty flame detection sensors

Repeated ignition faults usually require professional inspection.

4. Air Trapped in the Heating System
Air pockets restrict water circulation, causing overheating and shutdowns. Bleeding radiators improves circulation and helps prevent recurring boiler lockout issues.

5. Frozen or Blocked Condensate Pipe
During cold weather, condensate pipes can freeze or block. This prevents waste water from draining, stopping the boiler from firing. Carefully thawing the pipe may allow the system to restart.

6. Internal Sensor or Fan Faults
Faulty internal components are less common but serious. These faults should always be handled by a Gas Safe registered engineer.

Safety Checks Before You Reset Ideal Logic Combi 30 Boiler

Before attempting to reset Ideal Logic Combi 30 boiler, carry out these checks:

• Boiler pressure is between 1.0 and 1.5 bar
• Gas supply is active
• No visible leaks or unusual noises
• Electrical supply is stable

If any unsafe signs are present, do not reset the boiler.

How to Reset Ideal Logic Combi 30 Boiler (Step-by-Step)

Step 1: Locate the Reset Button
The reset button is on the front control panel, labelled “Reset”, “R”, or integrated into the dial.

Step 2: Check Boiler Pressure
Ensure pressure is within the safe range. Never perform an Ideal Logic boiler reset if pressure is too low or too high.

Step 3: Press and Hold Reset
Press and hold the reset button for 3–5 seconds, then release.

Step 4: Allow the Boiler to Restart
The boiler will attempt ignition. If successful, heating and hot water should resume shortly.

What to Do If Ideal Logic Boiler Reset Does Not Work

If the boiler immediately returns to lockout:

• Do not repeatedly press reset
• Recheck pressure and gas supply
• Note any fault codes

Persistent failure indicates a deeper issue requiring expert repair.

When You Should Stop Resetting & Call a Gas Safe Engineer

Contact OSO Group Engineers if:

• Boiler lockout keeps returning
• Pressure drops repeatedly
• Fault codes remain on display
• No heating or hot water after reset
• Unusual noises or leaks appear

Repeated resets can damage components and increase repair costs.

How to Prevent Future Boiler Lockouts

Annual Boiler Servicing
Routine servicing detects faults early and improves efficiency.

Monitor Pressure Regularly
Checking pressure every few weeks helps prevent unexpected boiler lockout situations.

Bleed Radiators When Needed
This removes trapped air and prevents overheating.

Insulate Condensate Pipes
Insulation reduces winter boiler failures caused by freezing.
