Fisher & Paykel Dishdrawer

Any assistance gratefully received.

I have a F&P Double Dishdrawer Model DD603H.

Yesterday I came into the kitchen to find the top drawer partially open. I pushed the drawer closed but it did not latch into place and slid open as soon as it is let go. There was a full wash waiting to go to i started the cycle going and the drawer remained shut, but as soon as I paused it and the lid raised it slid open again. There are no fault codes on display. I let the cycle continue and wedged a chair against it to stop it opening at the end of the cycle.

Any ideas for a home repair? I am happy to take the drawer out if necessary…I have watched many technicians do repairs over the 5 years we have had this machine!!! ( the only time I would recomend appliance insurance is if you own a F&P dishdrawer!)

Thanks for your help
