Mr. Coffee IDS40 - Manual (Page 6)

Cleaning Is A Must
Your coffeemaker must be delimed when you begin to notice an
increase in steaming. If the pumping action stops before all the
water has been pumped out of the machine, then the appliance
requires deliming.
The frequency of cleaning depends upon the hardness of water
used. The following table gives the recommended cleaning
intervals.
.
RECOMMENDED CLEANING SCHEDULE.
Type of Water Cleaning Frequency
Soft water every 80 brew cycles
Hard water every 40 brew cycles
Your coffeemaker may be delimed by using MR. COFFEE
or vinegar. For best results, use MR. COFFEE
CLEANER. It works better than vinegar and has no unpleasant
odor.
