Hi all I have a belling idw45 dishwasher that last night Monday (10/01/21) starting a bussing noise from the base of the unit. Sunday 9/01/21 I did a routine clean of dishwasher popped the cleaner in and run for cycle. I Regularly clean the filter and general keeping it clean. Topped up salts and rinse aid. I’m a kitchen fitter so know to keep clean etc to prolong life. I fitted this one 2ish years ago gets used every day. It’s drains ok and fills.
My wife tells me last night she had put something in which dropped down to hinder the spinning jets would this have caused something? Any help or links to videos would be helpful.
