Vokera E060 Fault Code: Causes, Fixes & Repair Costs
What does the Vokera E060 fault code mean?
The E060 code appears on Vokera boilers when the control board cannot obtain a reliable temperature reading from the domestic hot water (DHW) probe — also known as a thermistor. This small sensor continuously monitors the temperature of your hot water supply by measuring changes in its electrical resistance; as water heats up, resistance drops, and those readings are fed back to the PCB to regulate output. When the signal falls outside expected parameters — due to a failing sensor, damaged wiring, or a PCB issue — the boiler flags E060 and may display fluctuating hot water temperatures or refuse to produce hot water altogether.
General guidance only — not a substitute for professional advice, and not certified by a Gas Safe engineer. Always have your specific appliance assessed by a qualified professional. Any gas work must be carried out by a Gas Safe registered engineer. If you smell gas or suspect carbon monoxide, leave the property and call the National Gas Emergency line on 0800 111 999.
Common causes
- Faulty or degraded DHW thermistor Common
The NTC thermistor wears out over time and can begin sending resistance readings that are too high, too low, or erratic. The PCB interprets these as a probe fault and locks out DHW. This is by far the most common outcome when E060 persists after a reset.
- Loose or corroded wiring connections Common
The wiring loom connecting the DHW probe to the PCB can develop loose terminals or corrosion, particularly in older boilers or those in damp locations. A poor connection produces an intermittent or absent signal, which the boiler reads as a probe fault even if the sensor itself is still functional.
- DHW flow temperature exceeding safe limits Sometimes
If the hot water flow temperature climbs beyond the boiler's safe threshold — due to a stuck valve or a separate fault — the probe can trigger E060 as a protective response. Once the temperature normalises, the code may clear on a reset.
- PCB fault causing spurious sensor readings Rare
Occasionally the printed circuit board itself is responsible — a failed input channel or damaged component on the board can misread a perfectly healthy probe. This is typically only confirmed once the engineer has ruled out the sensor and wiring.
How to fix it
- Reset the boiler DIY safe
Press and hold the reset button (labelled R on most Vokera models) for 3–5 seconds until the fault code stops flashing, then release and allow the boiler to restart. On dial-control models, turn the selector to the reset or OFF/RESET position and hold briefly. If hot water returns and the code does not come back, monitor the boiler over the next day or two. Avoid resetting more than 2–3 times — repeated resets without a fix are not a solution.
- Check that your gas supply is active DIY safe
Confirm that other gas appliances in your home — such as a hob or gas fire — are working normally. If they are not, contact your gas supplier rather than resetting the boiler further.
- Call a Gas Safe registered engineer to inspect the DHW probe and wiring Gas Safe engineer
A qualified engineer will locate the DHW thermistor, check for loose terminals, and use a multimeter to measure the probe's resistance across a range of temperatures. A reading that falls outside the manufacturer's specification confirms the sensor has failed and needs replacing. This is a straightforward job and the most common resolution for E060.
- Engineer to test and replace the DHW thermistor if required Gas Safe engineer
Compatible NTC temperature sensors for Vokera boilers are widely available from heating spares suppliers. The engineer will fit a replacement probe, clear the fault code, and verify that hot water temperature control has returned to normal before leaving.
- Engineer to inspect the PCB if the fault persists after sensor replacement Gas Safe engineer
If E060 reappears with a new probe installed, the PCB input channel handling the DHW sensor signal may be faulty. The engineer will test the board and advise on repair or replacement. PCB work is always engineer-only territory and represents a more significant repair cost.
Parts you may need
- DHW NTC thermistor (temperature probe) · from £20
- Wiring loom / sensor harness · from £35
- PCB (printed circuit board) · from £220
The exact spare depends on your boiler's GC number (on the data badge). Check this against the part before buying.
Typical repair cost
Expect to pay roughly £100–£250, depending on the underlying cause.
Frequently asked questions
Can I fix the Vokera E060 fault myself?
The only homeowner-safe step is a boiler reset — press and hold the reset button for 3–5 seconds. If the code clears and hot water works normally, you may be fine. If E060 comes back, the probe, wiring, or PCB needs professional testing. Probes are internal components that require a Gas Safe registered engineer to access, test with a multimeter, and replace safely.
How much does it cost to fix a Vokera E060 fault?
For a straightforward DHW probe replacement you should typically expect to pay between £100 and £250 all-in, covering the call-out charge, labour, and the part itself (which is inexpensive — usually £15–£30). If the PCB turns out to be the root cause, costs rise significantly; a replacement PCB for a Vokera boiler commonly runs £180–£400 for the part alone, so total costs including labour could reach £350–£500 or more. Vokera also offer a fixed-price repair service that covers call-out, labour, and parts under warranty.
Will E060 stop my boiler heating my home as well as hot water?
E060 is specifically a domestic hot water probe fault, so central heating is often unaffected. Many homeowners notice the boiler continues to heat radiators normally but struggles to deliver consistent hot water temperatures or stops producing hot water altogether. That said, if the fault is severe enough the boiler may lock out entirely, so it is worth getting it looked at promptly.
How do I find a Gas Safe engineer to repair my Vokera boiler?
You can search for registered engineers in your area at gassaferegister.co.uk — the official UK authority for gas safety. Always ask to see an engineer's Gas Safe ID card before allowing work to start. Some engineers specialise in Vokera boilers, which can be worth asking about when booking, particularly if the repair may involve a PCB.
