Re: Upper basket spray arm jammed
Further update. I have taken the spray arm off and discovered the end hole was partially blocked by something that looked like cotton threads. I used a small pin and removed it and found that there was more. Approximately half a teaspoon of stuff came out. Since then the dishwasher has operated properly with no alarms so I think it’s fixed. Not sure where the gunk came from or how it got into the spray arm. 😀
