Error Presence of flame but without sufficient ionization (<3 μA) in Dietrich boiler

Error Presence of flame but without sufficient ionization (<3 μA) in Dietrich boiler

How to eliminate the mistake presence of flame but without sufficient ionization. Below you find a short description, possible causes and practical solutions to try before calling a technician.

Description

The boiler detects flame but the ionization current is below the required threshold (<3 μA). The appliance then stops for safety because the control cannot confirm a correct flame signal.

Cause

• Dirty or damaged ionization electrode (probe).
• Poor electrical connection, damaged wiring or bad grounding of the electrode circuit.
• Low gas pressure or partially closed gas supply (gas passage key not fully open).
• Faulty gas valve or control electronics.

Solution

• Check that the gas passage key is well open.
• Inspect and clean the ionization electrode; reposition or replace if worn or corroded.
• Verify wiring and connections between the ionization probe and the control board; ensure good grounding.
• Check gas supply pressure and the gas valve operation; replace faulty valve if necessary.
• If the control electronics or measurement circuit is suspected, notify a qualified technician to test and repair.
• Notify the professional to take care of the maintenance of the apparatus when the above steps do not restore correct ionization current.

Error Sense of the circulation of invested water in Dietrich boiler

How to eliminate the error sense of the circulation of water invested in Dietrich boiler. This fault indicates a problem with the hydraulic circulation required for the boiler operation.

Description

The boiler signals an abnormal or absent circulation of water in the system. This can prevent heat transfer and cause the unit to lock out for safety.

Cause

• Circulation pump stopped, blocked or electrically disconnected.
• Closed or incorrectly positioned valves (flow direction wrong).
• Air trapped in the circuit causing lack of flow.
• Partial blockage or obstruction in pipes or heat exchanger.

Solution

• Check the circulation (address, pump, valves).
• Ensure the circulation pump is powered and running; replace or repair a faulty pump.
• Verify valves are open and oriented for correct flow direction.
• Bleed air from the system to restore proper circulation.
• Inspect for blockages in filters, strainers or the heat exchanger and clean if needed.
• If the problem persists, contact a qualified technician to diagnose the hydraulic components.
