What DESCALE indicator
actually means.

On SteamCraft Ultra steamers a clean light timer runs while the unit heats. When it times down, the DESCALE indicator comes on to say scale has had time to build in the generator. Pressing the descale reset switch restarts the count once the generator has been descaled.

What to do when DESCALE indicator shows on the commercial appliance

Before you book,
in this order.

Each step comes from Cleveland's own guidance for DESCALE indicator on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Plan the descale for a quiet period; Cleveland's procedure takes a little over an hour of soak time.

02

Follow the SteamCraft descaling steps with the amount of descaler Cleveland lists for your model size.

03

Press the descale indicator reset switch after the procedure; if the light will not clear, or the steamer is slow even after descaling, book a visit.

Cleared?

The code is gone from the controller, the box pulls down to its set point and holds it, the vat or the cavity reaches temperature and recovers on schedule, the rinse hits its heat and the drum finishes its spin, all without a new part. If the same code comes back within a week, or during the next busy shift, mention it when you book.

What not to do

The DESCALE light is a scheduled reminder and does not mean the steamer has stopped working. A steamer that will not steam at all needs its power light, water and heat checked instead.

What you may
notice with it.

The commercial appliance problems DESCALE indicator tends to arrive with. Answer these at the commercial appliance before anyone is booked.

All problems

No repair indicated

Nothing to repair.

Nothing on the unit has broken; the controller is reporting a state it chose or one somebody set. A defrost pauses cooling for a scheduled melt and shows a warmer air reading for a while, a combi asks for a delime or runs its clean cycle and locks the door until it ends, a dish machine or a laundry machine sits in energy save between busy periods, and a door-open reminder beeps after a long delivery. No part is needed: letting the cycle finish, or the key sequence in the manual, brings the unit back.

In Cleveland's own words

When the clean light switch is depressed the clean light timer is reset.

Questions
about DESCALE indicator.

Can I clear DESCALE indicator myself?
Plan the descale for a quiet period; Cleveland's procedure takes a little over an hour of soak time.
Can we ignore the DESCALE light on a Cleveland SteamCraft?
The steamer keeps running, but scale keeps building on the heaters and probes. Over time that means slower steam and more service calls.
How much descaler does a SteamCraft Ultra 3 need?
Cleveland's chart lists half a gallon of its descaler for the Ultra 3 and a gallon for the Ultra 5. Larger models with two generators descale both at once.
Why did the DESCALE light come back so soon?
The light runs on a timer, not a scale sensor, so it returns after the same heating time whether the water is hard or soft. A water filter slows the scale but not the timer.

Back to your everyday

Still showing DESCALE indicator?

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
