Hi folks,
I have read through this site so I apologise if this is answered somewhere and I have missed it.
I have a Hoover DYN7164D1X. I am used to seeing error codes and my problem is not an error code issue.
Instead of showing the selected programme/ temp/ etc, my display flashes a seemingly random (but consistent) set of lights, and two option buttons illuminate as well.
I have slam door reset and this sometimes results in the normal display alternating with the random one. In the few seconds the normal data is displayed you can hear the machine trying to work (solenoid fill click) but then it stops when the random display shows.
From what I have read so far I am thinking maybe the PCB needs replacing. I can send a picture of the display if that might help.
Thanks, in anticipation. Ralph

AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hoover DYN7164D1X flashing inconsistent display due to electronic/control fault
- The problem
- A Hoover DYN7164D1X washing machine did not show a normal programme display consistently. Instead, it flashed a repeatable but seemingly random pattern of lights, with two option buttons illuminated. After a slam-door reset, the normal display sometimes appeared briefly and the machine could be heard attempting to start (including a fill solenoid click), but it then stopped when the abnormal display returned.
- Likely cause
- Most strongly supported diagnosis was an electronics fault, possibly involving the main PCB, the control panel board, a power-related issue, or the wiring/connection between boards. The exact failed component was not confirmed.
- What fixed it
- Advice was not to replace expensive PCBs speculatively because the fault had not been positively identified. The thread concluded that this was beyond sensible DIY repair without component-level testing knowledge and equipment. The owner decided against further repair and to replace the machine.
- Checks to try
- Slam-door reset tried
- Observed machine briefly showing normal programme information before reverting to the abnormal display
- Noted the machine attempting to start, including a solenoid fill click
- Confirmed the appliance can display normal fault codes such as E03, so the flashing pattern was not treated as a standard error code
- Parts or tools mentioned
- PCB
- Control panel board
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi. The lights could be an error code if the washing machine doesn’t display text on the control panel.

The machine displays error codes (such as E03) in the normal manner on the left of the control panel as you look at it.
As I said, this not an error code. I managed to attach a photo to my first post.
The machine flashes between the normal display for the programme selected and the pictured display (which appears to be random).
It would seem to be definitely an error with the electronics in some way. It could be a power issue or related to the PCB, but equally could be a fault on the control panel board itself. Or it could be a connection problem between the two. I always advise against speculatively replacing expensive PCBs, especially the main one. I've lost count of how many people have fitted one speculatively and found it did not cure the fault. It may even be something extremely simple like a faulty diode but without electronics knowledge and testing equipment it's impossible to know.

Thanks Andy,
In summary I think you are hinting that it is beyond sensible economic repair.
I could take a punt on the PCB but if that doesn’t work I’m back to square one and £50 lighter.
Appreciate the comments, but I guess she gets to buy a new machine.
We might take extended warranty on the new one ☹️
Hi. I'm saying it's beyond DIY repair unless you know how to test individual components on pcbs, which most appliance engineers don't - we are't taught to repair the pcbs, only to replace them. But having said that to pay an engineer to fit one would probably be halfway to a new one.
