Hi, I am just wondering how an end user gets to find out if there is any new firmware updates from the manufacturer to improve the operation of the Washing Machine or add new features or iron out bugs or new wash programmes or modify the already ones stored on the flash memory on the circuit control board.

Say in my case I bought a Hotpoint WMUD843P washing Machine back in 2012 and it has the slot on the back where the smartcard would go in- how would I know what firmware my washing machine has and wether the manufacturer (Indesit) has bought out any firmware (if any) since I have bought my washing machine. I think when I first bought the washing machine this particular model number had just come out so for all I know somewhere down the line Indesit might have brought out a firmware update to change the operation of the machine, or improved on the wash programmes, How would I know, or get to find out? - Thanks.

is the Firmware on this label at the back, or on a label on the control board itself?

Hotpoint WMUD843P firmware update query

The problem
The owner asked how an end user could identify the firmware version on a Hotpoint WMUD843P washing machine and find out whether Indesit had released any firmware updates or programme changes for the model via the rear smartcard-style slot.
Likely cause
No appliance fault was reported. The accepted reply indicates the rear slot is likely for a diagnostic tool rather than customer firmware updates.
What fixed it
The accepted advice was that the rear slot is understood to be for diagnostics only, not for end-user firmware upgrading. The reply also stated that appliance manufacturers generally do not make firmware updates available to customers, so there was no confirmed method given for checking or installing updated firmware on this model.
Checks to try
  • Rear slot identified in discussion as likely being for a diagnostic tool
  • Diagnostic tool reportedly only displayed the last error code

Hi. As far as I know the slot at the back is just for a diagnostic tool. I used to have one and all it did was display the last error code. The only manufacturer I can imagine bringing out firmware updates to improve their appliances are Miele and even then I don't expect they'd ever let customers do it. It's possible a manufacturer might be forced to modify something to fix an issue but again I'd be amazed if it was ever made available to the public. Appliance manufacturers just operate very differently.
