PROBLEM |
| PROBABLE CAUSE |
| REMEDY |
Inconsistent beverage level in |
| 1. Improper water pressure |
| Check operating water pressure to |
server/dispenser |
|
|
| the brewer. It must be between 20 |
|
|
|
| and 90 psi (138 and 620 kPa). |
|
| 2. Brew valve |
| Test the brew valve. Refer to test |
|
|
|
| outputs on page 40. Turn the valve |
|
|
|
| on for 30 seconds and collect the |
|
|
|
| water dispensed from the spray- |
|
|
|
| head. Repeat the test several times |
|
|
|
| to confirm a consistent volume of |
|
|
|
| dispensed water. If not consistent, |
|
|
|
| check the valve, tubing and spray- |
|
|
|
| head for lime buildup. |
|
| 3. Bypass valve |
| If bypass is being used on the incon- |
|
|
|
| sistent brew, test the bypass valve. |
|
|
|
| Refer to test outputs on page 40. |
|
|
|
| Turn the valve on for 30 seconds and |
|
|
|
| collect the water collected from the |
|
|
|
| funnel. Repeat the test several times |
|
|
|
| to confirm a consistent volume of |
|
|
|
| dispensed water. If not consistent, |
|
|
|
| check the valve, tubing and fittings |
|
|
|
| for lime buildup. |
|
| 4. Lime buildup |
| Inspect for lime buildup that could |
|
|
|
| block the tank, tank fittings, tubing, |
|
|
|
| valves and sprayhead. |
|
| 5. Brew volume adjustment |
| Adjust the brew volume, calibrate |
|
|
|
| sprayhead and bypass as required |
|
|
|
| to achieve the desired volume for |
|
|
|
| each brew cycle. |
