5.1.4 Fill Problem
Description – SYSTEM 1E Processor senses a full
condition in less than 54 seconds or takes longer than
five minutes to completely fill.
Action:
If less than 54 seconds to fill:
1. Check valves 2 and 3 failed open – replace.
2. Check LS3. (Refer to Figure 5-3.)
3. Check that A, B, and MaxPure™ Filters are in place.
If more than five minutes to fill:
1. Check that water supply is ON.
2. Check that water pressure supplied is within
specification.
3. Check that strainer in pressure regulator is clear.
4. MaxPure Filter may be clogged – replace.
5. If MaxPure Filter replacement does not correct
problem – replace A prefilter, then B prefilter if
problem persists.
6. Drain hose may be restricted – repair.
7. Faulty CK4/inlet screen – clean or replace.
8. Faulty SOL7 solenoid valve – replace. (Refer to
Figure 5-5.)
9. CK2 and CK3 may be stuck closed – replace.
10.Faulty LS3 – replace. (Refer to Figure 5-3.)
11. Low air pressure – check compressor.
12. Faulty LS5 – replace. (Refer to Figure 5-3.)
13. Faulty LS2 – replace.
14. Faulty SOL5 – replace. (Refer to Figure 5-5.)
5.1.5 Heat Problem
Description – SYSTEM 1E Processor takes longer
than the allotted time to heat the fluid to 46°C. (The
allotted time is determined by inlet water
temperature.)
Action:
1. Faulty HTR1 (resistance should be between
10 - 12 Ohms) – replace. (Refer to Figure 5-5.)
2. Heater thermal overload tripped – reset.
3. Faulty SSR1 – replace. (Refer to Figure 5-5.)
4. Faulty LS2 – replace.
5. Faulty control board – replace.
5.1.6 Temperature Under 45.5°C
Description – SYSTEM 1E Processor detects fluid
temperature of < 45.5°C during the exposure phase.
Action:
1. Faulty HTR1 – replace. (Refer to Figure 5-5.)
2. LS1 tripped – reset.
3. Faulty SSR1 – replace. (Refer to Figure 5-5.)
4. Faulty LS2 – replace.
5. Faulty control board – replace.
