Your advice came in very handy. We have had our Fisher & Paykel MW511 for almost 7 years already and up until now we couldn't get it to Spin and Lock as it just kept trying to pump the water out.
So, I followed your directions and what do you know, the 3rd, 4th and 5th leds were lit, so then we called the company and found out it just needed a little cleaning under the Aggitator.
And Yes, by cleaning under the Aggitator it then decided to Spin and Lock like it use to.
