Leisure H fault codewhat it means and how to fix it
Leisure publish something no other range cooker brand does: cut the power and the residual heat indicator goes out, leaving a hot zone with no warning on it.
Before you start
Has the cooker had power continuously since it was last used?
The right answer depends on what you can see. Pick the one that matches.
Choose the option on the left that matches what your appliance is doing, and the answer for that case appears here.
Has the cooker had power continuously since it was last used?
The display cannot be trusted as a guide to temperature at all. Leisure publish that the indicator will not light in this state and gives no warning.
Assume every zone that was used before the interruption is still hot, and keep hands and children away from the whole hob.
Has the cooker had power continuously since it was last used?
The indicator is doing its job and telling you the truth. It will clear itself as the zone cools, and there is nothing to reset.
Wait for the letter to go out, or make use of the warmth to hold something at temperature.
Has the cooker had power continuously since it was last used?
That is beyond what residual heat explains, and with no published threshold there is no way for you to test it from outside the appliance.
Try the published reset, and if the letter comes straight back on a cold hob report it to the support line as a sensor problem.
What H means
Leisure describe the indicator in one plain sentence: if H appears on the cooking zone display it means the cooking zone is still hot and may be used to keep a small amount of food warm. Then, in a boxed note, they publish the thing that makes this page worth writing. When power is cut off, the residual heat indicator will not light up and does not warn the user against hot cooking zones. No other brand researched in this category admits that in print, and it is the most safety-useful sentence in the Leisure documents, because the situations it describes are ordinary rather than exotic. A power cut. An RCD tripping while somebody uses a drill upstairs. Switching the cooker off at the wall to change an oven lamp, which is exactly what Leisure’s own troubleshooting tells you to do about a dead oven light.
In every one of those cases the glass is unchanged and the display is dark, and the only thing that has gone away is the warning. There is a sharper version of the same point, and it comes from Leisure’s own instructions rather than from us. Their published reset for a display that will not light is to disconnect the appliance at the circuit breaker, wait 20 seconds and reconnect it. Follow that instruction on a hob that has just been cooking and you have deliberately extinguished the residual heat indicator on a set of hot zones. Neither instruction is wrong; they simply have to be read together, and Leisure never put them on the same page.
What Leisure do not publish is a temperature. There is no threshold figure anywhere in this manual for when the letter appears or when it clears, which means you cannot estimate how hot the glass is or how long you have got. Other manufacturers in this category do publish figures for their own hobs, and those figures belong to those hobs. Borrowing one to fill the gap here would be inventing a fact, and it is precisely the sort of invented fact somebody puts their hand on. So the practical rule for a Leisure hob is a little more conservative than for a brand that gives you a number: while the letter is there, the zone is hot; when the letter is not there, you know nothing at all unless the cooker has had power the whole time.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| A zone has been used in the last few minutes | The ordinary case, and Leisure sanction making use of it to keep a small amount of food warm rather than treating it as a hazard only. | Common |
| No published threshold to judge it against | This manual gives no temperature and no duration, so the letter is the entire measurement available to an owner. | Common |
| The supply was interrupted while zones were hot | Leisure publish that the indicator will not light after power is cut, so a hot hob shows nothing whatsoever. | Occasional |
| Somebody isolated the cooker at the wall or the breaker | A deliberate switch-off has the same effect on the display as an outage, including when it is done to change an oven lamp. | Occasional |
| Leisure’s own 20-second reset has just been performed | Their published recovery for a dead display puts the hob through a power interruption, which is the condition that disables the warning. | Occasional |
What to try yourself
Leave the zone alone while the letter is showing. Leisure give no figure to argue with, so the indicator is the whole of the information.
Use the heat if you want it. Leisure say a zone showing the letter may be used to keep a small amount of food warm.
After any interruption to the supply, treat every zone as hot no matter how the display looks, because the warning does not survive a power cut.
Think twice about the timing of the 20-second circuit breaker reset. Doing it straight after cooking puts out the indicator on hot zones.
Keep children away from the hob for a good while after a power cut in particular, since there is nothing on the glass to warn them.
If the letter never clears, or appears on a hob that has been powered and unused for hours, note it and ring 0333 207 9918.
Get a qualified appliance engineer to look at your Leisure H
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

Nothing. This is an indicator behaving as documented, including when it fails to appear after a power cut, which is published behaviour rather than a fault to be repaired.

Common questions about Leisure H
How hot is the zone when the letter is showing?
Leisure do not say. There is no temperature anywhere in this manual for when the indicator appears or clears, and we are not going to substitute a figure another manufacturer published for a different hob. Treat it as hot enough to burn you, because that is all it is telling you.
Why does the indicator go out in a power cut?
Because the display needs electricity and the glass does not. The heat is in the ceramic surface and it stays there regardless of the supply; the letter is only a light. Leisure are unusually honest in printing the consequence, which is that the hob stops warning you at exactly the moment nobody is expecting it to.
The cooling fan is still running after I switched the hob off. Is the hob still hot?
The fan running on is published as normal in its own right: Leisure say it continues operating until the electronics in the hob cool down to a suitable temperature, and mark it as not a fault. It is telling you about the electronics underneath rather than about the glass, so use the zone indicators for the surface.
Can I really keep food warm on it?
Leisure say so, with the sensible qualification of a small amount of food. It is residual heat rather than a controlled setting, so it will fade, and it is not a substitute for the U keep-warm level if you want something held at temperature for any length of time.
