Water Hook-up
1) The water line may enter through holes on the rear or the bottom of the brewer. Use the right hand opening for water.
2) Use 3/8" copper or flexible water line to prevent strain. Do not use low temperature plastic tubing. The connection
to the fill valve is 3/8" flare.
3) Water line pressure must be from 30 to 70 psi.
4) Hot (up to 160°F) or cold water may be used. Hot water offers faster recovery between brews.
5) Install a shut-off valve near the brewer.
6) Installing a filtering system can improve the taste of brewed coffee and extend the life of the brewer. If your water
has high calcium (lime), chlorine, or iron content, this is especially important. The filter should be the lime inhibiting
type if cold water is used. Contact our parts department to select the filter for your conditions.
Prior authorization must be obtained from Grindmaster Corporation for all warranty claims.

Questions and answers
We have an P4000E that is brewing strong coffee, and partial air **** level. We don't hear additional water entering machine. We also don't get a second batch.
A possible cause for the Grindmaster P300E brewing strong coffee with partial air level and not producing a second batch could be:
1. Cold Shuttle: If the shuttle is not warm, it can lower the brewed coffee temperature and affect extraction, leading to strong coffee. Ensure the warmer is on and the shuttle is heated before brewing.
2. Incorrect Coffee-to-Water Ratio: Using too much coffee or too little water can result in strong coffee. Check that the correct amount of ground coffee is used (6.5–8 ounces per gallon of water).
3. Brew Valve Issue: A limed-up or faulty brew valve may restrict water flow, causing incomplete brewing. A visual check and possible cleaning or replacement of the valve may be needed.
4. Thermostat Set Too High: If the brew thermostat is set too high, the system may not function correctly for a second batch. Adjust the thermostat as needed.
5. Timer Fault: If the timer is not providing the correct voltage output for a second brew cycle, it may need to be checked and replaced.
Checking and addressing these potential issues should help resolve the problem.
