  Hotpoint Ultima Tumble Dryer Spares

We have purposely not listed any Hotpoint tumble dryer spares in this article as it covers multiple models from a vast range with numerous changes made to the spare parts used and subsequent replacement spare parts. They will also often look the same or similar yet be different or, look totally different yet be completely compatible as they've been altered.

Please, don't guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.

We would rather take the time to check for you and get it right.

  Hotpoint Ultima Tumble Dryer Fault Codes

These fault codes are written for tumble dryer repairers to troubleshoot problems and not for the general public by Hotpoint and they assume a certain level of competence on the part of the user in diagnostic routines. We have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits. For more help and advice on fault finding on a washing machine please refer to our basic fault finding guide from this link before you begin.

On the lower modesl in this range there is no digital display so you will get a binary code usin gthe built in LEDs or neon lights that give indications and options. These can vary from model to model but will be in the pattern shown in the chart below.

Indication Light Or LEDNumerical Value
Post Crease Care 16
Top left hand neon 8
Second neon down 4
Third neon down 2
Fourth neon down 1


This primarily relates to the Hotpoint tumble dryer model CTD40. This tumble dryer uses the same codes as CTD80 or CTD85 but does not have a digital display.

The codes are displayed by flashing the ON/OFF neon and a combination of the top four left hand neon’s and the Post Crease Care neon.

Each neon has a numerical value as shown in the chart above.

The bottom neon is not used for fault codes.

You add the value of the flashing neon’s and compare them to the fault codes for the CTD80 and CTD85 For example Neon’s second fourth from top are 4+1 = 5 this gives you fault code F05 and so on. From that you can determin ethe fault condition as shown below.

  More Hotpoint Tumble Dryer Help And Guidance

Should you need more help and guidance please use the links from this article as most of them will help you to understand your Hotpoint tumble dryer a lot better and probably very much help you in diagnosing the fault you have. Of course there are many other articles on the site that will also help you do this.

In addition you can post in our forums after registering but please do pay heed to the information below before doing so and read the guides, they are there to help you.

You must understand certain things before you begin or attempt any repairs on your own and we want to make these points very, very clear to anyone that decides to investigate one of these or any other tumble dryers:

  • We are not responsible for your safety, you are and by using this guide you accept that and accept that any damage that you may cause and work undertaken is entirely at your own risk.
  • We will advise the common causes of the fault codes but we cannot guarantee that any parts or work recommended will resolve the issue. It is entirely your responsibility to diagnose your particular problem and resolve it.
  • We are not responsible for you buying spares that do not resolve the problem, this is down to your own diagnosis not ours.
  • No warranty is inferred, implied or given.

You also have to understand that these Hotpoint tumble dryer fault or error codes are not a "magic bullet", they will not tell you what the problem is, they will only offer you an indication of where the problem lies and they are no substitute for good diagnostic skills. You can find out more about what fault codes actually tell you in this article. So please be well aware that, even with this new found knowledge you will still have to actually be capable of investigating and diagnosing the problem and this means adhering to basic appliance safety for working on them. 

Please do note that manufacturers can and do change fault codes without notice and we cannot guarantee that these error codes will apply to your particular model as all codes apply to a wide range of appliances and not normally any one specific model.

Hotpoint Ultima TCD970
Dryer switches on and display is fine. When I press start it tries to go but then causes the circuit breaker for the plug sockets to trip.
Any suggestions what the fault may be. We have just moved house and it worked fine before. I have cleaned it.

Kind regards,

ctd40g fault
if i go by the values listed above I get a code that doesn\'t exist as all listed lights are flashing, I did find a faulty element/thermostat which I have replaced but cant figure how to clear the fault code to test the machine
Colin Farrow
Blue displays flashing even after circuit board replaced, any ideas?
Colin Farrow
CTD8O TUMBLE DRIER (condenser drier)
After having changed the circuit board with display I still find the blue display is flashing. Is it supplied seperately or is my new circuit board faulty? Any suggestions!
It is extremely unlikely to be the new control board faulty, people change them a lot only to find they were never faulty in the first place and there\'s an article about that on here somewhere.

It will be something else that is faulty causing the error but you would really need to use the forums for more help with it.
