Tip & How-To about Washing Machines

Why Is WHIRLPOOL Duet & Duet HT washing machine showing ?Sud? error code on display?

The error Sud is shown on the display due to Overdose of Detergent detected during the Wash Cycle in the washing machine.
In this problem check the MCU in the washing machine. The motor control unit senses a suds lock. Also check the Drain pump for any blockage or the heavy load in the washing machine. or over quantity of detergent is added to the machine and that is got blocked.
This will Help. Good Luck.
