CODE25 Freezing and Mobile App Crashing


My CODE25 was repaired by Marshall in September after the amp itself kept crashing and the sound was cutting out. It has now been returned in an even worse condition.

On switching it on, the message 'Hold 'Store' to reset' appears on the screen. I press store and nothing happens. I am unable to access the amp presets.

After 10 minutes the mobile app then also freezes. I have contacted my Marshall dealer who sold me the amp and they have asked me to contact you for a resolution before I can send it back to them.

FYI: I have uninstalled and re-installed the mobile app without any resolution of the problem. The amp is is of no use and even a factory reset and firmware update has not solved the problem. I am gradually losing my faith in Marshall CODE products.

Do you have any solutions?

Hi Selena: am afraid to say that I am returning the amp to Marshall to get repaired for the second time. I will then be trying to get a part refund from shop in exchange for an Orange amp as I have had enough of Marshall. - Gerry McIntosh 13 Nov 2021 at 05:57 PM

Have a look at your colleague's message below and also my original post. There doesn't seem to be a lot of joined-up thinking here, hence my annoyance and changing to Orange.
I know you guys monitoring the forum are in the front-line and catching all the crap and are not responsible for badly manufactured amps. It is really your managers and those higher up that need to get their act sorted. And that includes developing products that don't fail so often.
