Falcon Which code table applies to a Falcona plain-English guide
Falcon and Rangemaster publish one troubleshooting section between them. The guides come from rangemaster.co.uk, share internal document numbers, and the code text matches word for word.
Before you start
Which sort of hob does your Falcon have?
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.
Which sort of hob does your Falcon have?
The published code set applies: E2 for the electronic unit being too hot, U400 for a cooker that has been incorrectly connected, and Er followed by a number for an internal fault the user cannot rectify. A dead display is published as over-voltage or loss of supply.
For E2, check ventilation around the cooker and whether a pan boiled dry; for U400 or Er, ring your installer or a qualified repair engineer. Do not read these against a Rangemaster built-in hob table.
Which sort of hob does your Falcon have?
There is no code table at all for you to find. The Deluxe 1000 Dual Fuel book was read end to end and its troubleshooting section is entirely narrative, with nothing numeric in it.
Stop looking for a code and work from the behaviour instead — the lighting procedure, the flame supervision device and the control layout.
Which sort of hob does your Falcon have?
Yours is the one book with extra content in the code block. It adds the child lock question to the will-not-switch-on list and phrases the mains question about the hob rather than the cooker.
Check the child lock before anything else if the hob will not respond, and use the 900S guide U110267-05c rather than a 1092 book.
What this means
If you have a code on a Falcon and you are wondering whether Rangemaster information is close enough to rely on, the answer is better than that. It is not an approximation, it is the same document. Three separate pieces of evidence say so. The guides themselves are served from rangemaster.co.uk, at the same path Rangemaster use for their own books and with document numbers from the same sequence, so downloading a Falcon manual means downloading it from the Rangemaster website. The books carry shared internal component references left in the page furniture, and the troubleshooting section in the Falcon Deluxe 1092 Induction guide and the troubleshooting section in the Rangemaster Toledo+ 110 Induction guide both sit under the label DocNo.050-0001 - Troubleshooting - Induction GENERIC. That module is named generic because it is one component dropped into both books rather than two sections written separately. And when the extracted text of the two is compared line by line, the code block is identical character for character, and the books share a typo elsewhere in their pages.
Because a claim like that ought to be falsifiable, here is every difference the comparison found in the code block. The Falcon 900S book adds a child lock line to its will-not-switch-on list, which the 1092 and the Toledo+ do not carry. The 900S phrases its mains question about the hob where the other two say cooker. And the capitalisation of the word Note differs. That is the complete list, and all three are model differences rather than brand differences. So what does the shared module actually say? Three codes and one blank screen. E2 is the electronic unit being too hot: check the installation of the cooker and make sure there is sufficient ventilation, and in extreme cases a utensil allowed to boil dry can produce it too. U400 is the cooker having been incorrectly connected: the control switches off after approximately one second and the code stays permanently displayed until your installer or a qualified repair engineer has been. Er followed by a number is an internal technical fault that cannot be rectified by the user. And no display at all is published as over-voltage or loss of supply voltage to the cooker. Every one of those routes to the installer or a qualified repair engineer, and the book adds who pays if the installer was at fault: you do. Now the caveat, which matters more for a Falcon than the badge on the door.
Rangemaster also publish guides for their built-in induction hobs, and those carry different tables from the range cooker module — tables built around other characters, E1, E5, E6 to E8, EA, EC and C1 to C8, whose meanings disagree even between the two hob guides. The Rangemaster pages on this site are built from those hob guides. So do not match a Falcon range cooker code against them: your table is the one in your own U-numbered guide, and the three codes above are the whole of it. U400 has its own cross-brand page in this category because five badges publish it; E2 and Er are given here. We deliberately do not republish the module a second time under a Falcon heading, because two copies of one article help nobody. A fourth data point rounds it off. AGA guides come off the same document platform as well, and the group’s New Zealand storefront is a single combined AGA and Falcon site, so this is one documentation estate wearing three badges rather than a coincidence between two of them.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| One shared troubleshooting module dropped into both books | The artwork label DocNo.050-0001 - Troubleshooting - Induction GENERIC heads that section in a Falcon book and in a Rangemaster book alike. | Common |
| Falcon guides are served from the Rangemaster domain | Every Falcon UK user guide found sits on rangemaster.co.uk, at the same path and with a document number from the same sequence. | Common |
| No working Falcon website to check against | The falconappliances domains fail their TLS handshake to a scripted client and return a server error to a browser, so nothing is published under the Falcon name. | Common |
| Model differences that look like brand differences | The 900S carries a child lock question the 1092 does not, which is about which controls the cooker has rather than about the badge. | Occasional |
| Third-party pages inventing a separate Falcon table | A code list published under the Falcon name with different meanings from the Rangemaster one cannot have come from a Falcon document. | Occasional |
What to try yourself
Find the U-number printed on your user guide. It looks like U110267-05c and it identifies the exact book your cooker was shipped with.
Download that guide from rangemaster.co.uk. There is no Falcon-hosted alternative, because the Falcon domains do not serve a site.
Look at the head of the troubleshooting section for the DocNo.050-0001 label. The 1092 book carries it; the 900S book carries the same text without the label.
Read your code against that section, not against a Rangemaster built-in hob guide: E2 is the electronic unit too hot, U400 is an incorrect connection, Er plus a number is an internal fault. The hob guides use different tables.
For an older manual, ring the number Rangemaster publish for customer services on 01926 457628. They answer Falcon questions in the first person.
Ignore any site offering a Falcon-only code list with different meanings. There is no document behind it.
Get a qualified appliance engineer to look at your Falcon range cooker
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 a documentation question and the answer is a free download. The cost it avoids is the real one: a wasted call-out because a code was matched against the wrong table, or a part changed on the strength of a meaning nobody published.

Common questions
Is Falcon just Rangemaster with a different badge?
The cookers are specified and sold as different ranges, but the documentation is one operation. They come from AGA Rangemaster Limited, the guides live on the Rangemaster website, the troubleshooting section is a shared component with the same internal number, and the code text is identical. For fault-finding purposes, treat them as one.
Why does falconappliances.com not load?
It fails at the TLS handshake for a scripted client and returns a server error to a browser, and the .co.uk variant does the same. That was the position on 8 August 2026 and again on 3 September 2026. It means there is no Falcon-hosted document to cite, and rangemaster.co.uk is the source of record: it also carries a Falcon range cooker product page.
Does the Rangemaster warning about two different tables apply to me too?
It applies in a different way, and it is the main reason to find your U-number. The two tables that disagree are in Rangemaster’s built-in hob guides, the Eclipse 90 and the RMB60HPEIGL, where E5 is an over-temperature in one and a mains voltage error in the other. Neither is your table. A Falcon range cooker carries the range cooker module, which publishes just E2, U400 and Er followed by a number, and in it E2 means the electronic unit is too hot. Read a hob table instead and you are reading meanings written for a different appliance, with characters your cooker will never show.
What about AGA — same codes as well?
Same document platform, different product and almost no published codes. AGA host their guides on the same kind of path, and the group runs a combined AGA and Falcon storefront in New Zealand, but AGA’s cast-iron cookers publish the format of an error code and no meanings at all. Do not carry a Falcon meaning across to an AGA.
