I am trying to understand an Eroor 11 code on these machines. Cryptically it indicates either wiring or the module is faulty. Has anone had experience of working on these machines? With this error code the machine neary does everything, so to me it indicates all the sensors are working, door interlock works, and motor/pumps/level sensors work ok. I have checked out all the wiring and all the obvoius things on the module, but can only come to the conclusion that the module needs reprogramming? Has anone else had any experiences with this model?

no it doesn’t dry since it is a hoover pos then it is a compromise, with an error 11 code it never actually finishes any cycle.
Re: Hoover HNWF7148 error codes
Now that’s what I would think, but there are no components ” burnt” and all measure to be within their tolerances. Since the machine nearly works, I am lead to the conclusion that the software on the processor IC is corrupt and this is halting the machine. There has to be a “hoover” expert out there that can provide some information on the main board, or offer a re-programming service. If i just change it, then that hasn’t really identified the fault.
youve had your answer
if it bothers you , ring hoover, if its under 5yrs old, theyll fit any part it needs for £99
expecting someone, expert or not to pinpoint your fault, without seeing the machine, or relying on your synopsis is somewhat ridiculous
Re: Hoover HNWF7148 error codes
Well there was an answer of sorts, but it doesn’t help with solving the problem and I wasn’t expecting an expert to “offer a fix” for the machine. The error 11 code can mean wiring, or faulty module acccording to GIAS. Ok so as a technician one would check the wiring with a meter, and assuming all the sensors worked according to specification by using a meter and hot water to alter their characteristics, one can assume these are working correctly as well. No the machine starts , fills, spins, empties, heaters start up ok etc, but it cannot finish a cycle. It”knows” how to start, but seems to be stopping after a set period. I can agree that by changing the module it would fix the machine, but since the module isn’t fried – meaning there are no damaged components, then all I can think is that the software is corrupt and all the module needs is re-programming. So as this discussion continues I would also add does anyone know of any differences between a 7148 machine core module and a 7166 core module, as they appear to be physically the same?
Re: Hoover HNWF7148 error codes
Coreboard programmed for HNWF7148 is p/no 09200828.
Coreboard programmed for HNWL7166 is p/no 09200706.The coreboard is a generic Candy part, which is factory programmed to specific parameters appropriate to each model. They can vary per model according to serial number in some instances.
As a repairer, I would arrive at a diagnosis of board failure after eliminating all other components and their wiring. That’s all any repairer needs to know before we fit a replacement board. We simply don’t have the time to get into board component level repairs.

Re: Hoover HNWF7148 error codes
I am going to go for the replace module approach. I wasn’t looking for a repair at board level, just checking that all the components on the board are ok, which they are, so it could be the software. espares used to sell an unprogrammed board , so where would anyone outside of the H/C organisation get one programmed up? on a last note before I shut up, where would i ask if anyone out there has any of these boards, presumably faulty? or do they send them back to H/C on an exchange basis?

Quote that number and your supplier should be able to order for you.

Re: Hoover HNWF7148 error codes
Received the new module, and it is slightly different, Fitted it and the machine nearly works exactly the same as before. It will start a cycle, but never finish. So now I’ll start replacing each part one by one untill it is fixed and then put back the others to see if the fault returns. Any one have the resistance readings readings for the sensors and heaters, , hot and cold?
Re: Hoover HNWF7148 error codes
You never answered my previous posted question icanfixthat did you? 😉
Re: Hoover HNWF7148 error codes
Oh sorry, no it doesn’t tumble dry. It starts and the heaters do switch on and the aluminium tube gets warm, and then it stops.

Hi: In your 4th post you say that you used a meter to test the sensors & hot water to alter their characteristics & one can assume the sensors are working correctly. How can you make this assumption if you had no idea of the correct sensor values to start with, especially the NTC? 😕
You mention also in your posts that the board couldn’t be faulty as there were no signs of burning or blown components. There do not have to be physical signs visible for an Electronic component to be faulty.
As you have already replaced the module without success wouldn’t it be a good idea to call an Engineer & save wasting more money?
